Question

How do you solve for x: `(x-3) /4 + x/2 =3`?

Answer 1

`x = 5`

Explanation:

In an equation with fractions, we can get rid of the denominators by multiplying each term by the LCD (LCM of denominators).
IN this case the LCM is `color(red)4`

`color(red)cancel4xx((x-3)) /cancel4 + color(red)cancel4^2xx x/cancel2 =color(red)4xx3`

`x-3 +2x = 12`

`3x =15`

`x =5`
