basic equation help!!
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' dimples Posts: 256, Reputation: 9 Full Member #2 Sep 1, 2005, 07:32 AM
I think there is something wrong with your equation. Do check it first shanus Posts: 17, Reputation: 0 New Member #3 Sep 1, 2005, 07:02 PM
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)
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 :) lost_and_confused333 Posts: 2, Reputation: 1 New Member #4 Sep 1, 2005, 08:15 PM
