I have the answer on my paper but I can't 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 :)

Thanks.. that helped a lot :)
