**PsyDAG**, Thursday, May 5, 2011 at 11:23am3x + 24y = 24

27x - 15y = -15

Divide both sides of the first equation by 3.

x + 8y = 8

Transpose 8y.

x = 8 - 8y

Substitute 8-8y for x in second equation and solve for y. Insert that value into the first equation and solve for x. Check by inserting both values into the second equation.
