# Homework Help: alg math 116

Posted by Juan on Monday, February 1, 2010 at 11:08pm.

y = 39 + 5x

9x + 3y = -51

Substitute 39 + 5x for y in the second equation and solve for x. Put that value in the first equation to solve for y. Check by putting both values in the second equation.

I hope this helps.
