All the said methods are unique on their on way. You are suggested to choose that method in which you are most comfortable in solving. However, you should know all the methods.

In the exam, it can be asked to solve questions using any particular method.

Cross multiplication method, for the equation

$a_{1} x + b_{1} y + c_{1} = 0 a_{2} x + b_{2} y + c_{2} = 0 \frac{x}{b_{1} c_{2} - b_{2} c_{1}} = \frac{y}{c_{1} a_{2} - a_{1} c_{2}} or � \frac{- y}{a_{1} c_{2} - a_{2} c_{1}} = \frac{1}{a_{1} b_{2} - a_{2} b_{1}}$
