9-4%283x%2B1%29=3%286-3x%29-9 Start with the given equation.


9-12x-4=18-9x-9 Distribute.


-12x%2B5=18-9x-9 Combine like terms on the left side.


-12x%2B5=-9x%2B9 Combine like terms on the right side.


-12x=-9x%2B9-5 Subtract 5 from both sides.


-12x%2B9x=9-5 Add 9x to both sides.


-3x=9-5 Combine like terms on the left side.


-3x=4 Combine like terms on the right side.


x=%284%29%2F%28-3%29 Divide both sides by -3 to isolate x.


x=-4%2F3 Reduce.


----------------------------------------------------------------------

Answer:

So the solution is x=-4%2F3 which approximates to x=-1.333.
