` ( 10 )/( x+ y) + (2 ) /(x - y ) = 4`,
` ( 15)/( x + y ) - (9) /( x - y) = - 2 `.

Solve the following simultaneous equations. (10)/(x + y) + (2)/(x -y) = 4 , (15)/(x + y) - (5)/(x - y) = - 2

Solve : (3)/(x + y ) + ( 2)/(x - y ) = 2 and (9)/(x + y ) - ( 4)/(x - y) = 1 .

{:((10)/(x + y) - (4)/(x - y)= -2),((15)/(x + y) + (7)/(x - y) = 10):}

{:((10)/(x + y) - (4)/(x - y)= -2),((15)/(x + y) + (7)/(x - y) = 10):}

If (10 x + 3y) : (5x + 2y) = 9 : 5 , then show that (2x + y) : (x + 2y) = 11 : 13 .

Solve for x and y : (x, y ne 0) (10)/(2x+y)+(3)/(2x-y)=3, (15)/(2x+y)+(9)/(2x-y)=6

Solve the following system of equations: (10)/(x+y)+(2)/(x-y)=4,quad (15)/(x+y)-(9)/(x-y)=-2
