5x + 6y = 18 2x - 3y = 12

As a first step in solving the system shown, Yumiko multiplies both sides of the equation 2x − 3y = 12 by 6.

By what factor should she multiply both sides of the other equation so she can add the equations and eliminate a variable?

What one-variable equation is she left with after adding?
