Question

If a pair of linear equations $a1x + b1y + c1 = 0$ and $a2x + b2y + c2 = 0$ has a unique solution, then which of the following conditions is correct?

Accepted Answer

For a pair of linear equations to have a unique solution, the ratio of the coefficients of $x$ and $y$ must not be equal, i.e., $\frac{a1}{a2} 
eq \frac{b1}{b2}$.
