The two sides are  "7b/12"  and  "4.2".

 

Original equation:                    7b/12  =  4,2

Multiply both sides by 12:  12(7b/12)  =  12(4.2)                      [The 12s on the left side cancel.]

Simplify:                                        7b  =  50.4

Divide both sides by 7:            (7b)/7  =  50.4/7                        [The 7s on the left side cancel.]

Simplify:                                          b  =  7.2
