One way of solving systems of linear equations is by adding a multiple of one equation to the other. The multiplier for one equation is chosen so that one of the two variables will cancel out in the sum. What should you multiply the equation by so that when added to the variable will cancel out?

Express your answer numerically. I need an explanation on the setup for this equation.
