### WARM-UP

Find the X and Y coordinate of the intersecting point via Substitution

2x + 2y = 38

y = x + 3

• 2x + 4x = 42

Solving Systems1. Graphing2.SubstitutionNOWSolving Systems by Elimination

HOW DO YOU ELIMINATE???

What

Variable

do

you

pick

and

WHY?

What is the Solution to the System

2x – 2 y = 8

3x + 5y = 24

What is the Solution to the System

3x – 5y = 4 6x-10y=8

-2x + 3y = 2 -6x+3y =6

-7y = 14

y= -2

A reminder that we’re focusing on Active Listening within your teams.

1. x+ y = 2

xy = 4

x 3y =3

2x + 3y = 5

3. Your math test has 38 questions and is worth 200 points. The test consists of multiple- choice questions worth 4points each and open-ended questions worth 20 points each. How many of each type of question are there?

It’s time now to do your work work, but you can check with team if you have a small question.

Ask Mr.Guidosif you have major issues at this point in class.
