Question

3. If 6x + 4 = 20 − 2x, then x = ?
a. 2
b. 6
c. 8
d. 16
e. 24

Answer 1

a

Explanation:

Your goal is to isolate the variable(x). If you subtract 4 from the left side and right side, then you are left with , 6x=16-2x. Then you add 2x to both sides to get 8x=16. Lastly divide both sides by 8 to get x=2. Hope this helps :)

Answer 2

a

Explanation:

`6x+4=20-2x`

Add 2 to each side

`8x+4=20`

Subtract 4 from each side

`8x=16`

Divide 8 by each side

`x=2`
