Yes, there was a mistake in applying the distributive property. If you have to perform
you have to multiply both terms in the parenthesis by 3, not just the first one.
So, the correct expansion would be

Step-by-step explanation:
y=-3+5x
substitute y into equation 2
3x-8y=24
3x-8(-3+5x)=24
3x+24-40x=24
x=0
y=-3+5(0)
y=-3
(x,y)=(0,3)
Answer:
should also be 40
