1. Rearrange terms.

12x-15=6-3x

12x-15=-3x+6

2. Add 15 to both sides.

12−15=−3+6

12−15+15=−3+6+15

3. Simplify

If you add the numbers you will get:

12x=-3x+21

4. Add 3x to both sides of the equation.

12x=-3x+21

12x+3x=-3x+21+3x

5. Simplify

If you combine the like terms you will get,

15x=21

6. Divide both sides of the equation by the same term.

15x=21

`(15x)/(15)` =
`(21)/(15)`

7. Simplify

If you cancel terms that are in both of the numerator and denominator, then divide the numbers you will get:

x=
`(7)/(5)`

I hope this helps :)
