Answer 1

Solve for x . 

7(4x−15)=63

(1 point)
x=

Answer 2

To solve for x, we need to isolate it on one side of the equation.

Multiply both sides of the equation by 8/3:
20 * (8/3) = -3/8x * (8/3)

Simplify the equation:
160/3 = -8x/3

Multiply both sides of the equation by 3:
(160/3) * 3 = (-8x/3) * 3

Simplify the equation:
160 = -8x

Divide both sides of the equation by -8:
160 / -8 = -8x / -8

Simplify the equation:
-20 = x

The solution is x = -20.

Answer 3

To solve for x, we need to isolate it on one side of the equation.

Start by distributing the 7 to the terms inside the parentheses:

28x - 105 = 63

Next, add 105 to both sides of the equation:

28x - 105 + 105 = 63 + 105

Simplify the equation:

28x = 168

To solve for x, divide both sides of the equation by 28:

(28x)/28 = 168/28

Simplify the equation:

x = 6

The solution is x = 6.
