Wrong anti-spam code

Formulation

Create the program that reads six real numbers \(a_{11}\), \(a_{12}\), \(a_{21}\), \(a_{22}\), \(b_1\), and \(b_2\) from the standard input and finds two real numbers \(x\) and \(y\) that are the solutions to the system \begin{eqnarray*} a_{11}x+a_{12}y&=&b_1\\ a_{21}x+a_{22}y&=&b_2. \end{eqnarray*} You are allowed to assume that the user will provide such input values that would guarantee that the system has unique solution.

Your code should replace the text // ??? // below

#include<iostream>
int main(){
    double a11, a12, a21, a22, b1, b2, x, y; 
    std::cin>>a11>>a12>>a21>>a22>>b1>>b2;
    // ??? //
    std::cout<< x<<" "<<y<<std::endl;      
    return 0;
}
