Question

8x + 3 (3 - x) = 34
A. x = 5
B. x = 2
C. x = 8
D. x = 4

Answer 1

A. x=5

Explanation:

8x+3(3-x)=34

We move all terms to the left:

8x+3(3-x)-(34)=0

We add all the numbers together, and all the variables

8x+3(-1x+3)-34=0

We multiply parentheses

8x-3x+9-34=0

We add all the numbers together, and all the variables

5x-25=0

We move all terms containing x to the left, all other terms to the right

5x=25

x=25/5

x=5

I think this is correct.

Answer 2

Answer: its A; x=5

Explanation:

8x+3(3-x)=34

distribute the 3 through the parentheses

8x+9-3x=34

then add the like terms

5x+9=34

subtract the 9 to the 34

you shoud get

5x=25

then divide the 5 on both sides and you get your answer of x=5
