[(57)/(x+y)+(6)/(x-y)=5],[(38)/(x+y)+(21)/(x-y)=9]

Solve the following system of equations by method of cross-multiplication: (57)/(x+y)+(6)/(x-y)=5,quad (38)/(x+y)+(21)/(x-y)=9

(14)/(x+y)+(3)/(x-y)=5,(21)/(x+y)-(2)/(x-y)=1

Solve the following simultaneous equations: 14/(x+y)+3/(x-y)=5,21/(x+y)-2/(x-y)=1

(x)/(2) - ( y )/(9) = 6, ( x) /( 7) + ( y ) /(3) = 5 .

Solve for x and y in the following question : 2/(x+2y)+1/(2x-y)+5/9=0, 9/(x+2y)+6/(2x-y)+4=0

x+(6)/(y)=6,3x-(8)/(y)=5 then y=………

(x-4)(x-3)=(x-6)(x-5) (y-9)(y-3)= (y-4)(y-3)

((x^(5y-3)xx x^(3-2y))/(x^(4y-6)xx x^(2y-9)))^(-4/3)= ______

If (3x -4y) : (2x -3y) = (5x -6y) : (4x -5y) , find : x : y .
