This is your review for your quiz on solving equations and inequalities tomorrow.

Here are the tasks that you will need to complete. Select the statements that are TRUE.:

• -Answer the question on the review paper. Show ALL work.

• - Enter your answer into each quizizz question to check your work.

• -Continue until you finish. (This is nearly identical to tomorrow's quiz. The numbers will be different.)

• I need to show ALL my work on the review paper.

• The Quizziz is to be used for checking my work.

• The quiz is TOMORROW.

• I should definitely guess every single one of the answers because that is a great way to study.

Mathematical Equivalence

ON

Answer explanation

1. 1. Add 5 to both sides.

2. 2. Divide both sides by 2.

3. 3. n=6

Mathematical Equivalence

OFF

Answer explanation

1. 1. Add nine to both sides.

2. 2. Multiply both sides by 3.

3. 3. BOOM! x=27

Mathematical Equivalence

OFF

Answer explanation

1. 1. Distribute the 6.

2. 2. Subtract 30 from both sides.

3. 3. Divide both sides by -6.

4. 4. BOOM 2/3 = a

Mathematical Equivalence

ON

Answer explanation

1. 1. Distribute the -1 outside the parentheses.

2. 2. Combine the 8y and -2y.

3. 3. Subtract 3 from both sides.

4. 4. Divide both sides by 6.

5. 5. BOOM y = 1.

Mathematical Equivalence

ON

Answer explanation

(This is just ONE way that you could solve it. There is more than one way to solve this problem.)

1. 1. Add five to both sides.

2. 2. Subtract 8n from both sides.

3. 3. Divide both sides by -6.

4. 4. n = -2

Mathematical Equivalence

ON

Answer explanation

There is more than one way to solve this equation. Variations, I should say.

1. 1. Distribute the 1/4.

2. 2. Add 5 to both sides.

3. 3. Subtract 4x from both sides.

4. 4. Divide both sides by 5

5. 5. x=4

• No solution

• Exactly one solution

• At least two solutions

• Infinitely many solutions

Answer explanation

Distribute/combine the terms on the left side of the equation. It should look just like the right. That means that it is infinitely many solutions.

Mathematical Equivalence

ON

Answer explanation

Divide both sides by 20.

You do NOT have to flip the sign.
