Solve: `5/(x+y)-2/(x-y)=-1,\ \ \ (15)/(x+y)+7/(x-y)=10` , where `x+y!=0` and `x-y!=0.`

( Solve: )/(x+y)-(2)/(x-y)=-1,quad (15)/(x+y)+(7)/(x-y)=10 where x+y!=0 and x-y!=0

Solve the following system of equations by method of cross-multiplication: (5)/(x+y)-(2)/(x-y)=-1,quad (15)/(x+y)+(7)/(x-y)=10 ,where x!=0 and y!=0

(xy)/(x-y)=(1)/(2);(xy)/(x+y)=(1)/(5) wherex +y!=0;x-y!=0

Solve (2)/(x) + (3)/(y) = 13, (5)/(x) - ( 4)/(y) = - 2 , where x ne 0 and y ne 0 .

Solve for x and y (5)/(x+y)+(1)/(x-y)=2 (15)/(x+y)-(5)/(x-y)=-2

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 (20)/(x + y) + (3)/(x - y) = 7 and (8)/(x - y)- (15)/(x + y) = 5 .

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

Solve (x+2)/(y+2)+2=0,(x-4)/(y-2)=(x-1)/(y+7)
