x-25=12x%2B9%2B3x Start with the given equation.


x-25=15x%2B9 Combine like terms on the right side.


x=15x%2B9%2B25 Add 25 to both sides.


x-15x=9%2B25 Subtract 15x from both sides.


-14x=9%2B25 Combine like terms on the left side.


-14x=34 Combine like terms on the right side.


x=%2834%29%2F%28-14%29 Divide both sides by -14 to isolate x.


x=-17%2F7 Reduce.

Answer:

So the answer is x=-17%2F7


Which approximates to x=-2.429
