[(8x+7y)/(xy)=15],[(10)/(x+y)+(2)/(x-y)=4],[(15)/(15)-(5)/(x)=-2]

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

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

(2)/(x)-(3)/(y)=15;-(8)/(x)-(5)/(y)=77

(2)/(x)-(3)/(y)=15,(8)/(x)+(5)/(y)=77

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

{:((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,quad (15)/(x+y)+(7)/(x-y)=10

Find x and y when (7x-2y)/(xy)=5,(8x+7y)/(xy)=15

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