a. 3x + 2 = 2(x + 2)      the idea is to get x by itself......simplify on the right

 

3x + 2   =  2x  +  4        subtract 2x,  2   from each side

 

x  =  2

 

 

b. 5x − 6 = 9x − 1 − 5x      simplify on the right

 

5x - 6  =  4x  - 1         add 6 to both sides, subtract 4x from both sides

 

x  = 5
