Question

How do you solve `\frac{5q-7}{12} = \frac{2}{3}`?

Answer 1

This can be solved using cross multiplication;

`(5q -7 ) / 12 = 2/3`

`(5q -7) * 3 = 2 * 12`

`15 q - 21 = 24`

adding `21` to both sides ;

`15 q -21 + 21 = 24 + 21`

`15q = 45`

dividing both sides by `15`

`(15 q) / 15 = 45 /15`

`q = 3`
