Question

(Variables on both sides of an equation)

Answer 1

Start by expanding the left side of the equation: -2(4x-7) is equal to -8x + 14.

This brings you to -8x+14 = -8x + 14.

Now add 8x to both sides. This brings you to 14 = 14

Now subtract 14 from both sides. This brings you to 0 = 0.

Thus your answer is 0 = 0, which is a true statement.

Hope this helps.

Answer 2

-8x + 14 = -2(4x - 7)
Open parenthesis and distribute
-8x + 14 = -8x + 14
Subtract both sides by 14
-8x = -8x
Subtract both sides by -8x
0=0
Thus, any value of x will satisfy the equation.
