solve 4(y-4)=8
1.
x / 4 + 1 = - 5 Subtract 1 to both sides
x / 4 + 1 - 1 = - 5 - 1
x / 4 = - 6 Multiply both sides by 5
x = - 6 * 4
x = - 24
2.
6 x + 29 = 5 Subtract 29 to both sides
6 x + 29 - 29 = 5 - 29
6 x = - 24 Divide both sides by 6
x = - 24 / 6
x = - 4
3.
- 21 a + 16a = - 5 a
4.
9 a - b - 2a - 10 b =
9 a - 2 y - b - 10 b =
7 a - 11 b
4 n + 7 + 2 n = 1
4 n + 2 n + 7 = 1
6 n + 7 = 1 Subtract 7 to both sides
6 n + 7 - 7 = 1 - 7
6 n = - 6 Divide both sides by 6
n = - 6 / 6
n = - 1
4 ( y - 4 ) = 8 Divide both sides by 4
y - 4 = 8 / 4
y - 4 = 2 Add 4 to both sides
y - 4 + 4 = 2 + 4
y = 6
Correction.
I forget - sign.
- 4 n + 7 + 2 n = 1
- 4 n + 2 n + 7 = 1
- 2 n + 7 = 1 Subtract 7 to both sides
- 2 n + 7 - 7 = 1 - 7
- 2 n = - 6 Divide both sides by - 2
n = - 6 / - 2
n = 3
1. To solve the equation x/4 + 1 = -5, we need to isolate the variable x.
First, we subtract 1 from both sides of the equation:
x/4 = -6
Next, we multiply both sides of the equation by 4 (to cancel out the division by 4):
4(x/4) = 4(-6)
x = -24
Therefore, the answer is D) -24.
2. To solve the equation 6x + 29 = 5, we need to isolate the variable x.
First, we subtract 29 from both sides of the equation:
6x = 5 - 29
6x = -24
Next, we divide both sides of the equation by 6:
(6x)/6 = (-24)/6
x = -4
Therefore, the answer is A) -4.
3. To combine like terms -21a + 16a, we need to add the coefficients of the like terms:
-21a + 16a = (-21 + 16)a = -5a
Therefore, the answer is -5a.
For the equation 9a - b - 2a - 10b, we can simplify it by combining like terms:
9a - b - 2a - 10b = (9a - 2a) + (-b - 10b) = 7a - 11b
Therefore, the answer is 7a - 11b.
To solve the equation -4n + 7 + 2n = 1, we need to simplify and isolate the variable n:
Combine like terms: -4n + 2n = -2n
Simplify equation: -2n + 7 = 1
Subtract 7 from both sides: -2n = 1 - 7
Simplify: -2n = -6
Divide both sides by -2: n = -6 / -2
Simplify: n = 3
Therefore, the answer is 3.
To solve the equation 4(y - 4) = 8, we need to simplify and isolate the variable y:
Distribute the 4: 4y - 16 = 8
Add 16 to both sides: 4y = 8 + 16
Simplify: 4y = 24
Divide both sides by 4: y = 24 / 4
Simplify: y = 6
Therefore, the answer is 6.
To solve the equation 4(y-4) = 8, you need to use the distributive property and isolate the variable y.
Step 1: Distribute the 4 to the terms inside the parentheses:
4 * y - 4 * 4 = 8
4y - 16 = 8
Step 2: Add 16 to both sides of the equation to isolate the term with the variable:
4y - 16 + 16 = 8 + 16
4y = 24
Step 3: Divide both sides of the equation by 4 to solve for y:
4y/4 = 24/4
y = 6
Therefore, the solution to the equation 4(y-4) = 8 is y = 6.
