5x-12%2B2x=22x-3 Start with the given equation.


7x-12=22x-3 Combine like terms on the left side.


7x=22x-3%2B12 Add 12 to both sides.


7x-22x=-3%2B12 Subtract 22x from both sides.


-15x=-3%2B12 Combine like terms on the left side.


-15x=9 Combine like terms on the right side.


x=%289%29%2F%28-15%29 Divide both sides by -15 to isolate x.


x=-3%2F5 Reduce.

Answer:

So the solution is x=-3%2F5
