If `(x+3,4-y)=(1,7),` then `(x-3,4+y)` is equal to

If log_(5)(3^(x)-4^(y))=3 and 3^((x)/(2))-2^(y)=5, then (x)/(y) is equal to

(4/(3)x-3/(4)y)^(3) is equal to

If ( 2x - 3y + 1)/(2) = (x + 4y + 8)/(3) = ( 4x - 7y + 2)/(5) then what is (x +y) equal to ?

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

Let y = y (x) be the solution of the differential equation ( x - x ^(3)) dy = ( y + y x^(2) - 3x^(4)) dx , x gt 2 . If y (3) = 3 then y (4) is equal to :

If (2+sin x)(dy)/(dx)+(y+1)cos x=0 and y(0)=1, then y((pi)/(2)) is equal to -(1)/(3)(2)(4)/(3) (3) (1)/(3)(4)-(2)/(3)

Let y(x) be the solution of the differential equation (dy)/(dx)+(3y)/(cos^(2)x)=(1)/(cos^(2)x) and y((pi)/(4))=(4)/(3) then vaue of y(-(pi)/(4)) is equal to (a)-(4)/(3)(b)(1)/(3)( c) e^(6)+(1)/(3)(d)3

If x=2,y=1 then x^(4)+2x^(3)y-2xy^(3)-y^(4) is equal to
