x%2B5-2x%2B4=3x-2%2B9x%2B15 Start with the given equation.


-x%2B9=3x-2%2B9x%2B15 Combine like terms on the left side.


-x%2B9=12x%2B13 Combine like terms on the right side.


-x=12x%2B13-9 Subtract 9 from both sides.


-x-12x=13-9 Subtract 12x from both sides.


-13x=13-9 Combine like terms on the left side.


-13x=4 Combine like terms on the right side.


x=%284%29%2F%28-13%29 Divide both sides by -13 to isolate x.


x=-4%2F13 Reduce.

Answer:

So the solution is x=-4%2F13
