−15x=120
Yes, −15x = 120 is a linear equation.
what is it simplifyied
To simplify −15x = 120, you can divide both sides of the equation by -15:
−15x / -15 = 120 / -15
This simplifies to:
x = -8
simply
x−25=19
To simplify x - 25 = 19, you can add 25 to both sides of the equation:
x - 25 + 25 = 19 + 25
This simplifies to:
x = 44
simply−3x+2=14
To simplify the equation -3x + 2 = 14, you can first subtract 2 from both sides:
-3x + 2 - 2 = 14 - 2
Simplifying further:
-3x = 12
To isolate the variable, you can divide both sides of the equation by -3:
-3x / -3 = 12 / -3
This simplifies to:
x = -4
−2y−8=15
To simplify the equation −2y − 8 = 15, you can first add 8 to both sides:
−2y − 8 + 8 = 15 + 8
This simplifies to:
−2y = 23
To isolate the variable, you divide both sides of the equation by −2:
−2y / −2 = 23 / −2
This simplifies to:
y = -11.5
5(x−2)=21
To simplify the equation 5(x - 2) = 21, you can start by distributing the 5 to both terms inside the parentheses:
5 * x - 5 * 2 = 21
This simplifies to:
5x - 10 = 21
Next, you can add 10 to both sides of the equation:
5x - 10 + 10 = 21 + 10
This simplifies to:
5x = 31
Lastly, to isolate the variable, you can divide both sides of the equation by 5:
(5x) / 5 = 31 / 5
This simplifies to:
x = 6.2
3x+19+7x+1=−200
To simplify the equation 3x + 19 + 7x + 1 = -200, you can combine like terms on the left side:
3x + 7x + 19 + 1 = -200
This simplifies to:
10x + 20 = -200
Next, you can subtract 20 from both sides:
10x + 20 - 20 = -200 - 20
This simplifies to:
10x = -220
To isolate the variable, you can divide both sides of the equation by 10:
(10x) / 10 = -220 / 10
This simplifies to:
x = -22
−25z+2=12
To simplify the equation −25z + 2 = 12, you can start by subtracting 2 from both sides:
−25z + 2 - 2 = 12 - 2
This simplifies to:
−25z = 10
Next, divide both sides of the equation by −25:
(−25z) / −25 = 10 / −25
This simplifies to:
z = -0.4
−2/5z+2=12
To simplify the equation -2/5z + 2 = 12, you can start by subtracting 2 from both sides:
-2/5z + 2 - 2 = 12 - 2
This simplifies to:
-2/5z = 10
To isolate z, you can multiply both sides of the equation by the reciprocal of -2/5, which is -5/2:
(-5/2)(-2/5z) = (-5/2)(10)
Simplifying further:
z = -25/2 or -12.5
2(4z+2)+5=40
To simplify the equation 2(4z + 2) + 5 = 40, you can start by distributing the 2 to both terms inside the parentheses:
2 * 4z + 2 * 2 + 5 = 40
This simplifies to:
8z + 4 + 5 = 40
Combine like terms:
8z + 9 = 40
Next, subtract 9 from both sides:
8z + 9 - 9 = 40 - 9
This simplifies to:
8z = 31
To isolate the variable, divide both sides of the equation by 8:
(8z) / 8 = 31 / 8
This simplifies to:
z = 31/8 or 3.875
−3x+4/2=5
To simplify the equation −3x + 4/2 = 5, you can start by simplifying the expression 4/2, which equals 2:
−3x + 2 = 5
Next, subtract 2 from both sides:
−3x + 2 - 2 = 5 - 2
This simplifies to:
−3x = 3
To isolate the variable, divide both sides of the equation by −3:
(−3x) / −3 = 3 / −3
This simplifies to:
x = -1
−3x+4 over 2 =5
To simplify the equation −3x + 4/2 = 5, you can first simplify the expression 4/2, which is equal to 2:
−3x + 2 = 5
Next, subtract 2 from both sides of the equation:
−3x + 2 - 2 = 5 - 2
This simplifies to:
−3x = 3
To isolate the variable, divide both sides of the equation by −3:
(−3x) / −3 = 3 / −3
This simplifies to:
x = -1
−16z−20=−12z+
I apologize, but the equation you provided is incomplete. There is an equal sign with no value or expression on the right side. Please provide the complete equation so I can assist you further.
−16z−20=−12z+8
To solve the equation −16z − 20 = −12z + 8, you can start by simplifying both sides:
−16z − 20 + 20 = −12z + 8 + 20
This simplifies to:
−16z = −12z + 28
Next, you can move all the terms containing z to one side:
−16z + 12z = 28
This simplifies to:
−4z = 28
Finally, to isolate z, divide both sides of the equation by −4:
(−4z) / −4 = 28 / −4
This simplifies to:
z = -7
3(4z+2)=2(5z−4)
To solve the equation 3(4z + 2) = 2(5z − 4), you can begin by distributing the 3 and the 2:
12z + 6 = 10z - 8
Next, you can move all the terms containing z to one side of the equation by subtracting 10z from both sides:
12z - 10z + 6 = 10z - 10z - 8
This simplifies to:
2z + 6 = -8
To isolate z, you can subtract 6 from both sides:
2z + 6 - 6 = -8 - 6
This simplifies to:
2z = -14
Finally, divide both sides of the equation by 2:
(2z) / 2 = -14 / 2
This simplifies to:
z = -7
2(5x+6)+2=−6x+_x+_
To solve the equation 2(5x + 6) + 2 = −6x + _x + _, please provide the missing values on the right side of the equation, as indicated by the underscore (_) symbols.
it dosent give u them u have to figure it out
I apologize for the confusion. To solve the equation, let's simplify both sides:
2(5x + 6) + 2 = −6x + _x + _
First, distribute the 2 to the terms inside the parentheses:
10x + 12 + 2 = -6x + _x + _
Simplifying further:
10x + 14 = -6x + _x + _
Next, combine like terms on the right side:
10x + 14 = (-6x + _x) + _
At this point, it is not possible to determine the exact values for the missing terms since the equation does not provide any information.
