Step-by-step explanation:
Multipy both equation with xy , you get :-
2y+3x=9 (1)
4y+9x=21 (2)
From equation one you get
3x=9-2y
x=9-2y/3
Substitr this in equation 2
4x + 9 (9-2y/3)=21
4x + 3(9-2y)=21 ( as u cut 9 by 3 )
4x+ 27-6y=21
-2y=-6
y=-6/-2
y=3
now put y=3 in x=9-2y/3
x=9-(2*3)/3
x=9-6/3
x= 3/3
x=1
