Vapor Pressure of Non-Ideal Solution

At a certain temperature, the vapor pressure of pure A is 101 and the vapor pressure of pure B is 54, both in mm. Hg. The vapor pressure of A (in solution) follows the equation
Vapor Pressure of A = 101 * (1 - 0.1*x - 0.9*x2)
and that of B follows the equation
Vapor Pressure of B = 54 * ( 0.2*x + 0.8*x2)
where `x' is the mole fraction of A in the solution. Calculate the mole fraction of A in the vapor if the mole fraction in the solution (x) is 0.45.
