Question

Find the value of x.
10
135-

Answer 1

Explanation:

`(x)/(12) = (x + 4)/(5 + 12) \\`

`(x)/(12) = (x + 4)/(17) \\`

Now cross multiply...

`12(x + 4) = 17x`

`12x + 48 = 17x`

`12x - 17x = - 48`

`- 5x = - 48`

Now divide both term by same number

`( - 5x)/( - 5) = ( - 48)/( - 5) \\`

`x = 9.6`
