1. 6-2B Solving by Linear Combinations Warm-up (IN) Learning Objective: to solve systems of equations using linear combinations. Solve the systems using substitution. (5,1) (-4,-2)

2. Notes Learning Objective: to solve systems of equations using substitution Ex 1 – Solve the system by linear combination 1 – line up like terms on top of each other 2 – multiply one, or both, of the equations so that one variable will cancel 3 – add the equations vertically 6 - Always write solution as an ordered pair!!! 5 – plug that value back into either of the original equations to find the other variable 4 – Solve for the remaining variable

3. Learning Objective: to solve systems of equations using substitution Try it! Pg. 404 a.

4. HW – p. 406 #2,3,10, p. 408 #27-29 Out – Which method of solving systems do you prefer? Explain why! Summary – I have a question about… POW!!
