(6)/(7*(6)/(x+y)-(7)/(x-y))=3,(1)/(2(x+y))-(1)/(3(x-y))=0;x+y!=0

Solve for x and y : (1)/( 7x ) + ( 1) /( 6y) = 3, (1)/( 2x) - (1)/( 3y ) = 5 (x ne 0, y ne 0)

Solve:(1)/(2(2x+3y))+(12)/(7(3x-2y))=(1)/(2)(7)/(2x+3y)+(4)/(3x-2y)=2 where 2x+3y!=0 and 3x-2y!=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 for x and y (2)/(x)+(2)/(3y)=(1)/(6),(3)/(x)+(2)/(y)=0

If (x,y) is a variable point on the line y=2x lying between the lines 2(x+1)+y=0 and x+3(y-1)=0, then ( a )x in(-(1)/(2),(6)/(7)) (b) x in(-(1)/(2),(3)/(7))( c) y in(-1,(3)/(7))(d)y in(-1,(6)/(7))

( 1 ) /(x) + (1 ) /( y) = 7 , ( 2)/(x) + ( 3) /( y) = 17 (x ne 0, y ne 0 ) .
