9x-(-2x) = 5x+4x-{2(x-10+3+7)}(-1) = 5x +2x-11x+22x-5x-x+x(-1)
= 11x

9x-(-2x)=9x+2x=11x
Subtracting a negative is the same as adding a positive. Just be careful if you have something like 9x-(-2x+3x). You will have to distribute the negative, so you'd have 9x+(2x-3x) or 9x+2x-3x=8x.
Hope that helps.

when you have a minus a minus number, change it to a plus
9x- (-2x) = 9x+2x

I would say:
9x - (-2x)
9x - - 2x
9x + 2x
11x

when you subtract its ALWAYS add the opposite. so its 9x+2x
and if it was something like -4-5
you would add the opposite so it would be -4+-5

9 x - ( - 2x) =
9 x + 18 x =

x - 9 x =
