Answer 2

Answer:

y = -1 and x = 3

Step-by-step explanation:

x - 2y = 5 -(1)

=> x = 5 + 2y

2x + y = 5 -(2)

Now, put x = 5 + 2y in eq(2)

2(5+2y) + y = 5

10 + 4y + y = 5

10 + 5y = 5

5 y = 5 - 10

5y = -5

y = -1

Now, put y = -1 in eq (1)

x - 2(-1) = 5

x - (-2) = 5

x + 2 = 5

x = 5 - 2

x = 3
