At the end of this lesson, students will be able to

1. align the terms of equations in a system and add the equations to eliminate a variable. Finally, solve for the remaining variable and use substitution to find the solution to the system.

2. align the terms of equations in a system and subtract the equations to eliminate a variable. Finally, solve for the remaining variable and use substitution to find the solution to the system.

3. aligne the terms of equations in a system, multiply to create opposite coefficients, add the equations then solve the system.

This lesson will entail adding, subtracting and multiplying equations with the goal of eliminating one variable and solving the systems of equations.
