3x+2y+14
2Y=-3X+14
Y=-3X/2+14/2
Y=-3X/2+7 (RED LINE)
2x+2y=16
2Y=-2X+16
Y=-2X/2+16/2
Y=-X+8 (GREEN LINE)
+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+12%2C+-3x%2F2+%2B7%2C+-x+%2B8%29+ (graph 300x200 pixels, x from -6 to 5, y from -10 to 12, of TWO functions -3x/2 +7 and -x +8).
-3X/2+7=-X+8
-3X/2+X=8-7
(-3X+2X)/2=1
-X/2=1
-X=2
X=-2
Y=-(-2)+8
Y=10 ANSWER.
