5X-4Y=-5 OR -4Y=-5X-5 OR Y=-5X/-4-5/-4 OR Y=1.25X+1.25 (RED LINE)
X-2Y=-7 OR -2Y=-X-7 OR Y=-X/-2-7/-2 OR Y=X/2+3.5 (GREEN LINE)
SOLUTION (3,5)
+graph%28+300%2C+200%2C+-6%2C+5%2C+-10%2C+10%2C+y+=+1.25x+%2B1.25%2C+y+=+x%2F2+%2B3.5%29+ (graph 300x200 pixels, x from -6 to 5, y from -10 to 10, of TWO functions y = 1.25x +1.25 and y = x/3 +3.5).
