What is the process of 'elimination' in algebra?

• When the graphs of two linear equations overlap and intersect at infinitely many points

What is the 'method of elimination' in solving systems of linear equations?

• It involves solving one of the equations for one variable and then substitifying that expression into the other equation

• It involves graphing the equations on the same set of axes and finding the point(s) of intersection

• It involves adding or subtracting the equations in order to eliminate one of the variables

• It involves multiplying each equation by a suitable number so that the two equations have the same or opposite coefficients for one variable
