Y-1/2x=3
Y-x=2

You can put this solution on YOUR website! How do you solve and graph the following linear equations:
8x-2y=-4
Y-1/2x=3
Y-x=2
y = x+2
-----------
To be solved, you need 2 eqns in 2 unknowns, 3 in 3, etc. Eqns in x & y come in pairs, not threes.
--------------
To graph them, find 2 points and draw a straight line thru them.
Y-x+2
Pick 2 values for x and solve for y
x...y
0...2 --> (0,2)
4...6 --> (4,6)
