By cross-multiplication, for $a_1 x + b_1 y + c_1 = 0,\; a_2 x + b_2 y + c_2 = 0$, the value of $x$ is —

Question

Accepted Answer

$\dfrac{b_1 c_2 - b_2 c_1}{a_1 b_2 - a_2 b_1}$

Answer

$\dfrac{c_1 a_2 - c_2 a_1}{a_1 b_2 - a_2 b_1}$

Answer

$\dfrac{a_1 b_2 - a_2 b_1}{b_1 c_2 - b_2 c_1}$

Answer

$\dfrac{b_1 c_2 - b_2 c_1}{c_1 a_2 - c_2 a_1}$
