Question

Simpllify -6x-12x please solve to get points

Answer 1

To do this combine like terms. Like terms are terms that have the same name, in this case, x. Therefore, pretend the x's aren't there and all you have is -6-12. Solve for that first, which is -18, then add the x back. The answer is -18x.
