Expand both sides of the equation.
To subtract the left side's x-term (2x) from both sides of the equation,
first put the left side's x-term on the stack.
3 -: - - - - - , - , (":"":C=-+-=S:"":")-/-=A""' - -=3""""
Then subtract 2x from both sides.
Collect the equation.
Each side is collected independently, and the x-terms cancel on the
Now you can isolate x in the equation. Specify the variable you want
