When you write equations to solve word problems, you
sometimes end up with two equations like Renard's or similar
x-2y=4
to the two equations at right. Notice that the second equation
y=-{x+4
is solved for y, but the first is not. Rewrite the first equation
in "y =" form, then solve this system of equations. Check your solution.
