How many solutions exist for the given equation?
3(x – 2) = 22 – x

Start by distributing the 3: 
(3)(x)+(3)(−2)=22-x

Now we have: 
3x−6=−x+22

Add x to both sides:
Add x to both sides.
3x−6+x=−x+22+x

Now we have:4x−6=22
Add 6 to both sides:

Add x to both sides.
3x−6+x=−x+22+x

4x−6+6=22+6

Now we have 
4x=28

Divide both sides by 4 
x=7
