Answer 1

`x = 14`

Explanation:

To find x, the following equation is generated given the available information:

`((x + 7) + x))/(x + 7) = (12 + 8)/(12)`

`(2x + 7)/(x + 7) = (20)/(12)`

`(2x + 7)/(x + 7) = (5)/(3)`

Cross multiply

`3(2x + 7) = 5(x + 7)`

`6x + 21 = 5x + 35`

Collect like terms

`6x - 5x = - 21 + 35`

`x = - 21 + 35`

`x = 14`
