dexar [7]4 years ago
5 0

Answer:

a= 2x <u><em>(edit: i just forgot it should be a integer x.x, forgive my blondiness)</em></u>

Step-by-step explanation:

usually when doing equations like that, you can separate one of the parenthesis with 0

(in this case, we will use (2x-a) )

Then create a equation, which should look like:

2x-a=0

Then solve for a

(-2x)2x-a=0(-2x)\\(-1)-a=-2x (-1) \\a=2x
