3x=8-2y

x=(8-2y)/3

3(8-2y)+2y=8

24-6y+2y=8

-4y=-16

y=4

3x+2(4)=8

3x+8=8

3x=0

x=0

3(0)+2(4)=8

x=0,y=4

-3x + 4y = 12; 3x - 5y = 18 Solve

viktelen [127]

X = -44

Solve for y in equation 1.
Plug in the new value for y into equation 2 to solve for x.
Next, plug your x value into either equation to find y. You can choose either, but I picked the 1st equation.
