Your first step is to use the Addition Property to get the variables on the same side of the equation.. If you mean something like 4x + 5 = 6x Add -4x to both sides: 5 = 2x then solve for x.

Sounds like a right triangle. use c^2 = a^2 + b^2 c = 20 a = 3x b = 4x 400 = 9x^2+ 16x^2 solve for x^2 and then take the square root to find x. Multiply this value times the 3 to find one side times the 4 to find the other side.
