1.	Let a,b,x and y be real numbers such that a−b=1 and y≠0. If the complex number z=x+iy satisfies Im(az+bz+1)=y, then which of the following is(are) possible value(s) of x?
Answer» Let $a, b, x$ and $y$ be real numbers such that $a - b = 1$ and $y \neq 0$ . If the complex number $z = x + i y$ satisfies $I m (\frac{a z + b}{z + 1}) = y$ , then which of the following is(are) possible value(s) of $x$ ?
