Answer:

0

Explanation:

2(–2x–8) –6x + ? = -2x + 13

-4x - 16 - 6x + ? = -2x + 13

-10x - 16 + ? = -2x + 13

To have infinitely many solutions, the coefficients of the variable x on both sides of the equation should be equal. In this case, the coefficient of x on the left side is -10, and on the right side, it is -2.

-10x = -2x

-10x + 2x = 0

-8x = 0

x = 0
