If x, y are rational numbers such that x+ y+(x-2y)sqrt2=2x-y+(x-y-1)sqrt6 then

If x, y are rational numbers such that (x+y)+(x-2y)sqrt(2)=2x-y+(x-y-1)sqrt(5) then

If x, y are rational numbers such that (x+y)+(x-2y)sqrt(2)=2x-y+(x-y-1)sqrt(5) then

4x-2y=3 6x-3y=5

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

Assertion : One of the rational number between (1)/(5) and (1)/(4) is (9)/(2) . Reason : If x and y are any two rational numbers such that x lt y , then (1)/(2)(x+y) is a rational number between x and y such that x lt (1)/(2) (x+y) lt y .

If x = (2)/(3) and y = (3)/(4), then a rational number (x – y) ^(-1) + (x ^(-1) – y ^(-1)) is equal to

If x = (2)/(3) and y = (3)/(4) , then a rational number (x-y)^(-1)+(x^(-1)- y^(-1)) is equal to

If x and y are rational and if x (3 + 2 sqrt2) - y sqrt2 = y(5 -3 sqrt2) + 7(2 + x sqrt2) , then find the value of x and y
