What expression is equivalent to -x + 5 - 13 + 12x

zvonat [6]

Answer:

11x - 8

Step-by-step explanation:

If you have x- + 5 - 13 + 12x, all we are doing is combining like terms. First, 5 - 13 = -8. Then, -x + 12x is the same as doing 12x - x. That gives us 11x. The answer would be 11x - 8 when you put -8 and 11x together in the expression.
