(10)/(x+y)+(2)/(x-y)=4,(15)/(x+y)-(5)/(x-y)=-2

Solve the following system of equations: (5)/(x+y)-(2)/(x-y)=-1,quad (15)/(x+y)+(7)/(x-y)=10

{:((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):}

Solve the following system of equations: 5/(x+y)-2/(x-y)=-1,\ \ \ \ \ (15)/(x+y)+7/(x-y)=10

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

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

(4)/(x) + (5)/(y) = 7 , (3)/(x) + (4)/(y) = 5
