You can put this solution on YOUR website!
I'm not sure what you want to do about the proofs, but I'm assuming that you want to solve for x.


3%283x-7%29=6 Start with the given equation.


9x-21=6 Distribute.


9x=6%2B21 Add 21 to both sides.


9x=27 Combine like terms on the right side.


x=%2827%29%2F%289%29 Divide both sides by 9 to isolate x.


x=3 Reduce.

Answer:

So the answer is x=3
