2x + 5y = -24 2x = -24 - 5y x = -12 - (5/2)y

The easiest approach to this kind of problem is to solve each equation for y. You should be able to do that. Then set the two non-y halves equal to each other. Example: y = 2x + 1 and y = 3x - 5 Set 2x + 1 = 3x - 5 Solve for x. Finally, plug the x into either of the y equations to get y. Done.
