Answer:
x=0, y = 3/2
Step-by-step explanation:
Ok, for substitution, you need to solve for y in terms of x, I'll do this for the first eqyation
8y=-7x+12
y=-7/8x+3/2, now plug in y in the second equation
-4x+2(-7/8x+3/2)=3, solve for x now
-4x-7/4x+3=3,
-4x-7/4x=0, x=0 now plug in 0 for either equation to solve for y
-4(0)+2y=3
2y=3, y=3/2
