Systems of Equations?

This is part of a Geometry Review thing.. haha. These two are just sorta weird since I haven't done Systems of Equations in a long time. x+3y=7 x+2y=4 9x-2y=50 6x-2y=32 It says to solve each system by the method of addition or subtraction. Thanks in advance! -Aubrey

x+3y=7 

x+2y=4 

Subtract the second from the first to get

y = 3

Now substitute this y value in either equation to find x.
