Answer:
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
