C-12-Q056mediumsingle_mcq

By cross-multiplication, the value of $y$ is —

a $\dfrac{b_1 c_2 - b_2 c_1}{a_1 b_2 - a_2 b_1}$
b $\dfrac{c_1 a_2 - c_2 a_1}{a_1 b_2 - a_2 b_1}$
c $\dfrac{a_1 b_2 - a_2 b_1}{c_1 a_2 - c_2 a_1}$
d $\dfrac{c_1 a_2 - c_2 a_1}{b_1 c_2 - b_2 c_1}$

ব্যাখ্যা

From the same cross-multiplication relation, $\dfrac{y}{c_1a_2 - c_2a_1} = \dfrac{1}{a_1b_2 - a_2b_1}$ , so $y = \dfrac{c_1a_2 - c_2a_1}{a_1b_2 - a_2b_1}$ .

By cross-multiplication, the value of $y$ is —

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

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

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

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

ব্যাখ্যা

From the same cross-multiplication relation, $\dfrac{y}{c_1a_2 - c_2a_1} = \dfrac{1}{a_1b_2 - a_2b_1}$ , so $y = \dfrac{c_1a_2 - c_2a_1}{a_1b_2 - a_2b_1}$ .
