Multiply the first equation by 2
4x-6y=16
Then add the equations to eliminate x
4x-6y=16
-4x+5y=-10
-y=6
y-=6
Plug the y value in
2x-3(-6)=8
2x+18=8
2x=-10
x=-5
Final answer: (-5,-6)
2x -3y = 8 ---> y = 2/3x +-8/3
-4x +5(2/3x + -8/3) = -10
-4x + 10/3x + -40/3 = -10
-2/3x + -40/3 = -10
plus 40/3 on both side = -2/3x = 10/3
multiply both side by 3/-2 = -5
x = -5 y = -6
y = sub x into orginal equation
