Answer:

x = 3 and y = - 1

Step-by-step explanation:

1a.  2x + y = 5          Solve for y in the first equation.

           y = -2x + 5

1b.   2(-2x + 5) = 2x - 8

       -4x + 10 = 2x - 8

         -6x + 10 = -8

         -6x = -18

1c.          x = 3

       2y = 2x - 8      

       2y = 2(3) - 8

       2y = 6 - 8

        2y = -2

           y = -1

Check  Use x = 3; y = -1

1d.      2x + y = 5                    2y = 2x - 8

        2(3)  - 1 = 5                   2(-1) = 2(3) - 8

         6 -  1 = 5                      -2 = 6 - 8

            5 = 5                         -2 = -2             Checked
