Use the algebraic strategies you developed in today's lesson to solve the system of equations at right. Be sure to check your solution.
Choose a pair of equations that can be added together to eliminate a variable.
Choose a different pair of equations to add together to eliminate the same variable.
In this case, you will have to multiply each equation by a constant.
Solve the system of equations you created in steps
Then substitute the values for
Check your solution in a different equation than the one you used to solve for
