There are three different methods..
1. Is subsⁿ i.e. eliminate x or y from any of the eqn. And put it in the other one.. U will get a eqⁿ in variable by this.
Other is quiter easy and trickier .. Make the any of the x or y coffecient of both the eqⁿs same. And subtract them to each other..
And last is cross multiplication.. Which is moyhing but cross product of the eqⁿs..
