## 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???

WHY?

Warm Up Day 2

What is the Solution to the System

2x – 2 y = 8

3x + 5y = 24

### MENTAL MATH / FIND THE GOOF

What is the Solution to the System

3x – 5y = 4 6x-10y=8

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

-7y = 14

y= -2

### Team Huddle

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

### Solve for X and Y by Elimination

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?

### Team Mastery

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.
