Algebra 1: Module 11 Lesson 4
Bellwork: More Maff StuphExplain: 1) Understand the need for an alternate method of solving systems than substitution and graphing. 2) Use ELIMINATION to solve systems of equations 3) Be able to manipulate equations to make elimination work outPractice: WorksheetPresentations: Closing:

11.2:SolvingSystems ofLinearEquations2) Substitution
y = 3x + 10
y = x 2
Solve by Substitution. Then identify if this is a consistent (independent or dependent) or inconsistent system.

Solve by Substitution. Then identify if this is a consistent (independent or dependent) or inconsistent system.
8x 4y = 16
6x + 2y = 14From
Yesturday
4y = 8x 16 y = 2x + 4Step 1: Change 1 equation to SI
Step 2: Substitute and Solve
6x + 2(2x + 4) = 146x + 4x + 8 = 14
2x + 8 = 142x = 6x = 3
Step 3: Plug x into one equation
6x + 2y = 14 6(3) + 2y = 1418 + 2y = 14
2y = 32 y = 16WOW, like... srsly???
I'm exhausted!
