Question

NEED QUICK 50 POINTS

Answer 1

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.
