i have the answer on my paper but i cant figure out how to do the problem itself

a c
-(2x - 12)= -
b d

its 'a' over 'b' times 2x minus 12 equals 'c' over 'd'

I think there is something wrong with your equation. Do check it first

I'm assuming you are trying to solve for x???

(a/b)*(2x-12) = (c/d)
multiply both sides by b
a*(2x-12) = (cb/d)
divide both sides by a
2x - 12 = (cb/da)
add 12 to both sides
2x = (cb/da) + 12
divide both sides by 2
x = (cb/2da) + 6

with these sorts of questions, you become better at them with practice and practice alone...they might be tedious, but any effort made in practicing will pay off in an exam
