#1) Set them up as y=mx+b
2x+y=4 -subtract 2x on both sides
NEW: y= -2x+4
3x+2y=1 -subtract 3x on both sides of equation
New: 2y= -3x+1 -Divide 2 on both sides (to get Y by itself)
NEW: y= -3/2x + 1/2
Set both Y equation equal to each other
-3/2x+1/2 = -2x+4
solve for x
you should then get x = 7
plug in x=7 into one of the equations to get y
