Answer 2

Answer:

x is 3 and y is 2

Step-by-step explanation:

x + y = 5

x = 5 - y ----------------(1)

2x - y = 4

2x = 4 + y

x = 4 + y/2 ------------------(2)

in both equations LHS is equal so RHS can be equated

5 - y = 4 + y /2

10 - 2 y = 4 + y

6 = 3y

y = 2

from equation (1) ,

x = 5 - y

x = 5 - 2

x = 3
