he equation −3x−9=−21 is solved as follows. Supply the correct numbers to complete the solution.(1 point)
−3x−9=−21
−3x= Add 9 to both sides.
x= Divide both sides by −3.
−3x−9=−21
−3x= -21 + 9 (Adding 9 to both sides)
−3x= -12
x= -12/-3 (Dividing both sides by -3)
Therefore, the solution is:
x = 4
The equation 10x+13=−12 is solved as follows. Supply the correct numbers to complete the solution.(1 point)
10x+13=−12
10x= Subtract 13 from both sides.
x= Divide both sides by 10.
10x+13=−12
10x= -12 - 13 (Subtracting 13 from both sides)
10x= -25
x= -25/10 (Dividing both sides by 10)
Therefore, the solution is:
x = -2.5
Solve 5−6x=−7 .(1 point)
x=
To solve the equation 5−6x=−7, we need to isolate the variable x.
First, subtract 5 from both sides:
5 - 5 - 6x = -7 - 5
-6x = -12
Next, divide both sides by -6:
-6x / -6 = -12 / -6
x = 2
So the solution to the equation is x = 2.
The equation 5/3x+11/3=−4/3 is solved as follows. Fill in the correct numbers to complete the solution.(1 point)
5/3x+11/3=−4/3
53x= Subtract 113 from both sides.
x= Multiply both sides by 35, the reciprocal of 53.
To solve the equation 5/3x + 11/3 = -4/3, we need to isolate the variable x.
First, subtract 11/3 from both sides:
5/3x + 11/3 - 11/3 = -4/3 - 11/3
5/3x = -15/3
Next, we need to multiply both sides by 3/5, the reciprocal of 5/3:
(3/5)(5/3x) = -15/3 * (3/5)
x = -45/15
Simplifying the right hand side:
x = -3
So the solution to the equation is x = -3.
The equation 0.24x−0.74=−1.1 is solved as follows. Fill in the correct numbers to complete the solution.(1 point)
0.24x−0.74=−1.1
0.24x= Add 0.74 to both sides.
x= Divide both sides by 0.24.
To solve the equation 0.24x - 0.74 = -1.1, we need to isolate the variable x.
First, add 0.74 to both sides:
0.24x - 0.74 + 0.74 = -1.1 + 0.74
0.24x = -0.36
Next, divide both sides by 0.24:
(0.24x) / 0.24 = -0.36 / 0.24
x = -1.5
So the solution to the equation is x = -1.5.
