- 15x - 10 - x + 3 = - 16x - 20 + 13 \\ - 16x - 7 = - 16x - 7 \\ 0 = 0
This means the solution to the equation is "all real numbers". Try substitute x with any value you will get the same solution for both side. So this equation happens to have an infinite number of solutions.

Answer: All Real Numbers

Explanation:

5(-3x - 2) - (x - 3) = -4(4x + 5) + 13

-15x - 10 - x + 3 = -16x - 20 + 13 distributed

-16x - 7 = -16x - 7 added like terms

-7 = -7 added 16x to both sides

TRUE

This makes a true statement so there are infinite solutions.
