Solving Equations, Part II (Systems and Inequalities)
... Solving Systems of Linear Equations: For each of the pairs of equations, first choose which approach is likely easier to solve the system of equations (substitution or addition). Then use that approach to solve the system of equations for both x and y. And finally check your work by substitutin ...
