In the cross-multiplication arrangement $\dfrac{x}{b_1c_2-b_2c_1}=\dfrac{y}{c_1a_2-c_2a_1}=\dfrac{1}{a_1b_2-a_2b_1}$ , the quantity $a_1b_2-a_2b_1$ is the determinant $D$ that acts as the common divisor. Since $x=D_x/D$ and $y=D_y/D$ both use it and it also sits under the $1$ , it serves as the denominator of $x$ , $y$ , and $1$ .
