Step-by-step explanation:
3x + 2y = 11 - (1)
2x + 3y = 4 - (2)
Add (1) and (2)
5x + 5y = 15 - (3)
Divide equation (3) by 5
x + y = 3 - (4)
Subtract (1) and (2)
3x + 2y - ( 2x + 3y ) = 11-4
3x + 2y - 2x - 3y = 7
x - y = 7 - (5)
Add (4) and (5)
x + y + x - y = 3 + 7
2x = 10
x = 5
Put x = 5 in (4)
5 + y = 3
y = 3 - 5
y = -2
