Question 72497
2x+3y=1, 3y=-2x+1, y=-2x/3+1/3
5x+3y=16, 3y=-5x+16, y=-5x/3+16/3 (these forms are for graphing) now subtract. 
-------------------------
-3x=-15
x=-15/-3
x=5 answer. now substitute 5 for x & solve for y
2*5+3y=1
10+3y=1
3y=1-10
3y=-9
y=-9/3
y=-3 answer.
{{{ graph( 300, 300, -10, 10, -10, 10, y = -2x/3 +1/3, y = -5x/3 +16/3) }}} (graph 300x300 pixels, x from -10 to 10, y from -10 to 10, of TWO functions y = -2x/3 +1/3 and y = -5x/3 +16/3).
