# 1

4a-%28a%2B6%29=12-36 Start with the given equation.


4a-a-6=12-36 Distribute.


3a-6=12-36 Combine like terms on the left side.


3a-6=-24 Combine like terms on the right side.


3a=-24%2B6 Add 6 to both sides.


3a=-18 Combine like terms on the right side.


a=%28-18%29%2F%283%29 Divide both sides by 3 to isolate a.


a=-6 Reduce.

Answer:

So the answer is a=-6





# 2

You forgot an equal sign.




# 3


2x-3%28x-9%29-2%28x-3%29=0 Start with the given equation.


2x-3x%2B27-2x%2B6=0 Distribute.


-3x%2B33=0 Combine like terms on the left side.


-3x=0-33 Subtract 33 from both sides.


-3x=-33 Combine like terms on the right side.


x=%28-33%29%2F%28-3%29 Divide both sides by -3 to isolate x.


x=11 Reduce.


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

Answer:

So the answer is x=11
