The given equation is 

             (Using distributive property: a (b+c) =ab+ac)

                      (Multiply: 4(2) =8; 3(4) =12)

     (Subtract 3n from each side)

     (Using commutative property:a+b=b+a)

                           (Subtract:)

               (Add 8 to each side)

                                   (Add:)

                               (Divide each side by -7)

                                          (Cancel common terms) \ \
