Question

How do you solve `\frac{3}{4} ( 3x + 9) = 62`?

Answer 1

`x=221/9`

Explanation:

To eliminate the fraction multiply both sides of the equation by 4.

`cancel(4)^1xx3/cancel(4)^1(3x+9)=4xx62`

`rArr3(3x+9)=248`

now distribute the bracket.

`9x+27=248`

subtract 27 from both sides.

`9xcancel(+27)cancel(-27)=248-27`

`rArr9x=221`

To solve for x divide both sides by 9.

`(cancel(9) x)/cancel(9)=221/9`

`rArrx=221/9" is the solution"`
