What is the first step for elimination?
Step 1 : Add (or subtract) a multiple of one equation to (or from) the other equation, in such a way that either the x -terms or the y -terms cancel out. Step 2 : Then solve for x (or y , whichevers left) and substitute back to get the other coordinate.

What is the example of elimination method?
Both the variables get eliminated. For example, let us solve two equations 2x-y=4 __ (1) and 4x-2y=7 __ (2) by the elimination method. In order to make the x coefficients equal in both the equations, we multiply equation (1) by 2 and equation (2) by 1. By doing so we get, 4x-2y=8 __ (3) and 4x-2y=7 __ (4).
