Answer:

Step-by-step explanation:

One

2x + 3 = 8x - 5                Add 5 to both sides

2x + 3 + 5 = 8x               Combine

2x + 8 = 8x                      Subtract 2x from both sides.

8 = 8x - 2x                       Combine

8 = 6x                              Divide by 6

x = 8/6

x = 8.333

Two

3x + 2 = 4                       Subtract 2 from both sides

3x = 4 - 2

3x = 2                             Divide by 3

x = 2/3

2y + 6 = 5                     Subtract 6 from both sides

2y = 5 - 6

2y = -1                          Divide by 2

y = - 1/2

x + y = 2/3 - 1/2

x + y = 4/6 - 3/6

x + y = 1/6
