Answer 1

Answer: Multiply both sides by 3x +7

Then -12

Explanation:

Answer 2

A)Multiply both sides by 3x + 7.

Reset

A)the solution of the equation is x=-12

Explanation:

Hello

let

to begin isolating we must multiply both sides by 3x + 7.

Reset

this way

`(-22+3x)/(3x+7)=2\\(-22+3x)/(3x+7)*(3x+7)=2*(3x+7)\\-22+3x=2*(3x+7)`

let´s continue to find x

`\\-22+3x=2*(3x+7)\\-22+3x=6x+14\\-22-14=6x-3x\\-36=3x\\x=(-36)/(3)\\ x=-12`

the solution of the equation is x=-12
