Objective: I know how to solve system of equations by multiplication and then addition or subtraction.

Sometimes, none of the coefficients of the variables are opposites or equal. However, it may be possible to multiply one of the equations with a number that will then make the coefficients of one of the variables opposites or equal. We can then add or subtract the equations to eliminate one of the variables.

Look up the lesson on Solving System of Equations if you need help on solving system of equations.
