a%2B%28a-3%29=a%2B2-%28a%2B1%29 Start with the given equation.


a%2Ba-3=a%2B2-a-1 Distribute.


2a-3=a%2B2-a-1 Combine like terms on the left side.


2a-3=1 Combine like terms on the right side.


2a=1%2B3 Add 3 to both sides.


2a=4 Combine like terms on the right side.


a=%284%29%2F%282%29 Divide both sides by 2 to isolate a.


a=2 Reduce.
