4. which set of expressions below does not
represent equivalent expressions?
a. 8(3x + 7) and 8(3x) + 8(7)
b.) 3(8x + 7) and 11x + 10
c. 7(3x + 8) and 7 - 3x + 7.8
d. 3(7x + 8) and 2 1x + 24

x+y = 29, 5x + 2y = 100

step-by-step explanation:

i'm guessing it was a multiple first option was the correct answer

heyyy

step-by-step explanation:

b. would be the answer : )

step-by-step explanation:

step 1: add -16x to both sides.

16x−4y+−16x=64+−16x  

−4y=−16x+64

step 2: divide both sides by -4.

−4y /-4 = -16x + 64/-4

answer:   y=4x−16

hope i'm right
