Question

Simplify expressions
2=3/4x-7

Answer 1

x = 12

Explanation:

2 = 3/4x - 7

2 + 7 = 3/4x

9 = 3/4x

9 × 4x = 3

36x = 3

x = 36/3

x = 12

Answer 2

Answer: x = 12

Explanation:

`2=(3)/(4)x-7`

Add 7 on both sides to get rid of the 7 and isolate x.

`+7+2=(3)/(4)x-7+7`

`9=(3)/(4)x`

Now multiply both sides by
`(4)/(3)` to eliminate it and isolate x.

`((4)/(3))(9)=((3)/(4)x) ((4)/(3))`

`12=x`

Proof;

`2=(3)/(4)x-7\\2=(3)/(4)(12)-7\\2=9-7\\2=2`
