Answer:

A, D

Explanation:

(1/4)(8x + 56) = 20

A.

(1/4)(8x + 56) = 20

Multiply both sides by 4.

8x + 56 = 80

56 + 8x = 80

Yes

B.

(1/4)(8x + 56) = 20

2x + 14 = 20

2x = 6

x = 3

The original equation has solution x = 3.

14 = 20 - 8x

8x = 6

x = 6/8 = 3/4

Solution is different.

No

C.

2x + 14 = 5

2x = -9

x = -9/2

Solution is different.

No

D.

2x = 6

x = 3

Solution is equal.

Yes
