Is the equation always, sometimes, or never true?

2x + 3 (x - 4) = 2 (2x - 6) + x

So the answer is x=-1

2x + 3 (x - 4) = 2 (2x - 6) + x

Distribute 3 inside the parentheses.

2x + 3x - 12 = 2 (2x - 6) + x

Distribute 2 inside the parentheses.

2x + 3x - 12 = 4x - 12 + x

Combine like terms on the left side.

5x - 12 = 4x - 12 + x

Combine like terms on the right side.

5x - 12 = 5x - 12

This statement is TRUE, so your answer is: Always true
