Answer 1

`9x- 60=10`

Explanation:

Given

`(3)/(4)x - 5 = (5)/(6)`

Required

Rewrite to remove fractions

The denominators in the above expression are 4 and 6.

So, first we take the LCM of 4 and 6

`LCM = 12`

Next, multiply both sides of the equation by this LCM (12)

`12 ( (3)/(4)x - 5) = (5)/(6) * 12`

`12 * (3)/(4)x - 12 *5 = (5)/(6) * 12`

`3 * 3x- 60=5 * 2`

`9x- 60=10`
