Question

18. (3) Given equations are ( x+y=7 ) and ( 3 x-2 y=11 )
On multiplying Eq. (i) by 2 and then adding Eq. (ii), we get
[
5 x=25
]
( Rightarrow quad x=5 )
( therefore quad 5+y=7 )
( Rightarrow quad y=2 )

# 18. If x + y = 7 and 3x - 2y =11, then (1) x = 2, y = 5 (2) x = 5, y = 5 (3) X = 5, y = 2 (4) x = 0, y = 3

Solution
