The process of elimination, which is also called a linear combination in math, is when you create coefficients that are additive inverses and add two equations vertically so that one variable is eliminated. From there, you'll have only one equation with one variable to solve. Look to use elimination if you see that the coefficients are already additive inverses or an equation could easily be multiplied by some constant to make some coefficients additive inverses.
