Answer:
y = 80
x = 5
Hope this helped :)
Explanation:
Lets say x + 5 so,
y = 8(5) + 12
y = 40 + 12
y = 52 so now we go back to the top equation which would be,
16(5) - 2(52) = -24
80 - 2(52) = -24
80 - 104 = -24, true
Therefore, any number you put in will still get you -24 so your answer is correct if you do substitution right.
