Question

If pair of linear equation
${a}1x1 + b1y \: and a2 + b2y + c2 = 0$
in two variables have unique solution then correct relation among the following is a
$\frac{a1}{a2 } = \frac{b1}{b2?}$
$\frac{a1}{a2} = \frac{b1}{b2 } = \frac{c1}{c2}$
​

Answer 1

Step-by-step explanation:

For equations S
