solution of the equations (1)/(x)+(1)/(y)=4 and (1)/(x)-(1)/(y)=0

If y(x) is a solution of (dy)/(dx)-(xy)/(1+x)=(1)/(1+x) and y(0)=-1 , then the value of y(2) is

If y(x) is a solution of (dy)/(dx)-(xy)/(1+x)=(1)/(1+x) and y(0)=-1 , then the value of y(2) is

1/(3x+y)+1/(3x-y)=3/4 and 1/(3x+y)-1/(3x-y)= -1/4

y: (1) / (x + 1) + (1) / (y + 1) = 10; (1) / (x + 1) - (1) / (y + 1) = 4

The solution of (dy)/(dx)=(1)/(2x-y^(2)) is given by , (A) y=Ce^(-2x)+(1)/(4)x^(2)+(1)/(2)x+(1)/(4)," 4"(1)/(2)," (B) "x=Ce^(-y)+(1)/(4)y^(2)+(1)/(4)y+(1)/(2)," (C) "x=Ce^(y)+(1)/(4)y^(2)+y+(1)/(2)," (D) "x=Ce^(2y)+(1)/(2)y^(2)+(1)/(2)y+(1)/(4)

The solution of (dy)/(dx)+(2x)/(1+x^(2))y=(1)/((1+x^(2))^(2)) given that x=1,y=0 is
