Today's Lesson: Solve Systems by Substitution

Objective:
I can solve a system of linear equations by substitution.

Solve the linear system of equations using substitution.

Solve by Substitution, then Graph it!

Solve the system by substitution, then graph it to confirm the solution you found.

Solve the system of equations. Show all work.
3x+7y=21
y = x - 7

y = 2x + 11
y = -3x + 1

CHALLENGE! (only do this one after you finish the rest of the Formative questions)

Solve the system by substitution, then graph it to confirm the solution you found.
