[" 34."(3)/(x)-(1)/(y)+9=0],[(2)/(x)+(3)/(y)=5(x!=0,y!=0)]

( 3 ) /(x) - (1 ) /( y) + 9 = 0 , (2)/(x) + ( 3)/( y) = 5 ( x ne 0 , y ne 0 )

(3) / (x) - (1) / (y) + 9 = 0 (2) / (x) + (3) / (y) = 5, (! = 0, y! = 0)

Solve by cross-multiplication method. (i) 8x-3y=12,5x=2y +7 (ii) 6x+ 7y -11 =0, 5x+ 2y =13 (iii) (2)/(x)+(3)/(y) =5, (3)/(x) -(1)/(y) +9=0

Solve by cross-multiplication method (2)/( x) + ( 3)/( y ) = 5, ( 3)/( x ) - (1)/( y ) + 9 = 0

( 5)/(x)- ( 3) /( y ) = 1 , ( 3) /( 2 x ) + ( 2) /( 3y ) = 5 ( x ne 0 , y ne 0 )
