Question

Which value for x makes the sentence true?

Answer 1

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

Answer: D. x = 2

Answer 2

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

$8x+4=20$

$-4-4$

$20-4=16$

$8x=16$

$\div8\div8$

$16\div8=2$

$x=2$

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

Hope this helps.
