Question 678292: How do you turn this equasion into y=mx+b for graphing?
3x+-2y=2
-2x+y=8
With an answer of (-18,-28)

Starting with 3x + -2y = 2
Isolate the y
3x + - 2y + 2y = 2 + 2y
3x = 2 + 2y
3x - 2 = 2 + 2y - 2
3x - 2 = 2y
Divide the entire equation by 2
y =
...
Starting with -2x + y = 8
-2x + y + 2x = 8 + 2x
...
Setting the quations equal,
Multiply the entire equation by 2
3x - 2 = 4x + 16
Isolate the x on one side of the equation
3x - 2 - 3x - 16 = 4x + 16 - 16 - 3x
-18 = x
...
Using x equals -18, solve for y in either of the equations
y = 2(-18)+8 = -36 + 8 = -28
...
(-18, -28)
