Answer:

Step-by-step explanation:

x

x + 0.5 = 2x - 3.5                       Subtract x from both sides.

0.5 = 2x - x - 3.5

0.5 = x - 3.5                               Add 3.5 to both sides.

0.5 + 3.5 = x - 3.5 + 3.5

4 = x

y

y + 2 = 2y - 2.8                          Subtract y from both sides.

2 = 2y-y - 2.8

2 = y - 2.8                                  Add 2.8 to both sides.

2 + 2.8 = y - 2.8 + 2.8

y = 4.8

The length of the sides

Using x: x + 0.5 = 4 + 0.5 = 4.5

Using y: y + 2 = 4.8 + 2 = 6.8
