(a) Add 1 to both sides, and we have:

                               x\ =\ 1

(b) Transposing 1 to the RHS, we have:

                                x\ =\ -\ 1

(c) Transposing - 1 to the RHS, we have:

                               x\ =\ 6

(d) Transposing 6 to the RHS, we get:

                               x\ =\ -\ 4

(e) Transposing - 4 to the RHS, we have:

                               y\ =\ -\ 3

(f) Transposing 4 to the RHS, we get:

                               y\ =\ 8

(g)  Transposing 4 to the RHS, we get:

                               y\ =\ 0

(h) Transposing 4 to  the RHS, we get :

                               y\ =\ -\ 8
