Answer:
The answer to your question is: x = -2/5 y = -31/5
Step-by-step explanation:
7/2x−1/2y=9/2 (1) Multiply by 2
3x−y=5 (2)
2 ( 7/2x−1/2y=9/2 ) = 7x -1y = 9
7x -1y = 9 (1) Multiply by (-1)
3x−y=5 (2)
-7x + y = -9
3x − y = 5
10 x = -4
x = -4/10
x = -2/5
3(-2/5) - y = 5
-6/5 -y = 5
y = -6/5 -5
y = -6/5 - 25/5
y = -31/5
