Answer:
2x + y = 11 - - - - - - - - - (1)
x + y = 8 - - - - - - - - - - (2)
From equation 1,
2x + y = 11
2x = 11 - y
x = 11 - y /2 - - - - - - - - - - (3)
Putting Equation (3) in equation (2)
x + y = 8
11-y/ 2 + y = 8(
11 - y /2 + y /1 = 8
11 - y + 2y / 2 = 8
11 - y + 2y = 16
11 + y = 16
y = 16 - 11
y = 5 - - - - - - - - - - - - - (4)
Putting equation (4) in equation (2)
x + y = 8
x + 5 = 8
x = 8 - 5
x = 3 - - - - - - - - - - - - (5)
From equation (4) & (5)
we get,
x = 3
y = 5
