#(3,2)#

The solution of a system of equations is the point where the functions intersect.

When you graph the two equations, you get:

The solution is #(3,2)#.

If you're having trouble graphing the equations, put them into #y=mx+b# form.

#x-2y=-1#

#=>-2y=-x-1#
#=>y=1/2x+1/2#

#3x+2y=13#

#=>2y=-3x+13#
#=>y=-3/2x+13/2#
