Question 234069
You are already given what y equals in the 2nd equation, just plug that into the 1st equation and solve for x.

2x-3(-4x+24)=-2

2x+12x-72=-2

14x=70

x=5

now plug this into the 2nd equation to solve for y.

y=-4(5)+24

y=-20+24

y=4

plug both numbers back into both orginal equations to verify.
