Which value for x makes the sentence true?
8x + 4 = 20
a. x = 12
b. x = 4
c. x = 8
d. x = 2

8x+4= 20

move +4 to the other side

sign changes from +4 to -4

8x+4-4= 20-4

8x= 20-4

8x= 16

divide both sides by 8 to get x by itself

8x/8= 16/8

Cross out 8 and 8, divide by 8 and then becomes 1*1*x= x

x= 16/8

D. x = 2

In order to get the answer to this question you will have to solve the equation before you can get the answer.

Therefore your answer is option D "x = 2."

Hope this helps.

the answer is d. 75%

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
