### Unit 3, Week 3

Multi-Step Equations

• Pick up your guided notes and tracker and respond to the following SILENTLY & INDEPENDENTLY:

• Solve for c. -10 + ½c = 30

• Solve for x. (4/x) – 20 = 40

• STILL MISSING! – letter issued with report cards & Stanford Math letters!

• MISSING WORK! – Post along the back wall. All work is deducted 10% after every day it is late. After 10 days, the work can no longer be turned in. Check now so it doesn’t affect your grade later and you can’t make it up!

• RETAKING QUIZZES! – If all your homework is not turned in for the topics covered on the quiz, you MAY NOT retake a quiz. Prepare yourself adequately and you will more than likely not need to retake a quiz!

With Multi-Step Equations it can be hard to know where to start…. pretend it’s a party!

• You are the host - a.k.a. ‘X’

• In what order do people leave a party

• Enemies (get rid of them to avoid trouble) – TOMORRROW!

• Acquaintances (after mingling with everyone, they usually leave early)]

• Friends (they hang out with the host a little longer)

• Family (if attending, they will stay to the end to help clean)

Who is who?Consider our one-step equations

FAMILY….right beside you…and only you… until the end!

2x = 8

x +3 = 15

x – 5 = 20

FRIENDS….they are close to you…they stay longer than some people, but not as long as family

ACQUAINTANCE –

Because this number mingles with all other many parts of the equation instead of giving most of its attention to the host (x), it is not a friend…it is an acquaintance.

FRIEND

FAMILY

ACQUAINTANCE

EXAMPLE 1:

The work:

ACQUAINTANCE – multiply each side of the equation by 3.

The result:

We still have company... lets continue….

Friends – add 5 to each side.

The work:

The result:

All that is left is family…a familiar one-step equation.

Clean up the party with a family member!

The work:

Family – divide each side by 2

The result:

Don’t forget to check your work with Order of Operations!

Its party time!Do you know who is in your home?

Family

HOST

Friend

Enemy

The Door!

Acquaintance

See if you can ID the enemy, the friend, the acquaintance, a family member, the host and the door!

Example 1

Its easy to spot an enemy…they affect everything!

To solve, multiply each side by the reciprocal( the fraction flipped)
