Simpllify -6x-12x solve to get points

-20x
since both are negatives you have to combine them

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.
