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

(xy)/(x+y)=6/5 ; (xy)/(y-x)=6

Solve the following system of equations: (7x-2y)/(x y)=5,\ \ \ (8x+7y)/(x y)=15

When x=5 and y=2 , the expression (xy)/(70)+(9)/(5(x+y))+(1)/(x+y)=?

{:(2x + y = (7xy)/(3)),(x + 3y = (11xy)/(3)):}

Find (x)/(y) , when x^(2) + 6y^(2) = 5xy .

Find value of x and y: (5x-4y+8=0),(7x+6y-9=0)

Find value of x and y: (5x-4y+8=0),(7x+6y-9=0)

Simplify and find the value of the simplified expression when x=-1 and y=2. 4(x^2+3y^2)-(9xy-[5(2x^3-3y^2)+xy)]

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

Solve : {:(x+y=7xy),(2x-3y=-xy):}
