2. Identify the Properties

=(3)

5(1) = 5

(3 ∙2 ) ∙𝑥=3 ∙ (2 ∙𝑥 ) Associative Prop of Mult.

Symmetric Property

Multiplicative Identity

3. Three times the difference of 7 and x

3(7-x)

4. Twice the sum of 3 and x2(3 + x)

Modeling Words with an Algebraic Expression

5. for x = – 3, y =– 2 = = = =

Evaluating Algebraic Expressions

6. 35 – 8x = 3 – 8(x – 4)35 – 8x = 3 – 8x + 3235 – 8x = – 8x + 35 + 8x + 8x

35 = 35ALWAYS TRUE!!!

Infinite Solution!!

Solve a Multi-Step Equation

7. +3 +3

2x = 60 2 2x = 30

Solve a Multi-Step Equation

(5)(5)

Solve for x.8.

x(2 + 3y) = 6y2 + 3y 2 + 3y

Solve a Literal Equation

9. – 3x + 4 > 10

- 4 - 4- 3x > 6 - 3 -3

x < -2

Solve & Graph Inequalities

FLIP!!!

(2)(2)

10. -4x + 2 > - 22 and 6x – 7 > 47

-2 -2 +7 +7 -4x > -24 and 6x > 54

-4 -4 6 6x < 6 and x > 9

Not Possible!!No Solution

Solve & Graph Inequalities

FLIP!!!

11. 6 fewer than a number is at least 10

x – 6 10

12. Twice the difference of 3 and a number is no more than 15

Write an Inequality from a Sentence

13.

3x + 2 = 2 or 3x + 2 = - 23x = 0 3x = - 4x = 0 or x =

Solving an Absolute Value Equation

14. -72 +2 +2

-707 7

-10No Solution!

Solving an Absolute Value Inequalities

15. - 26 - 20

4 – x < 5 and 4 – x > - 5-x < 1 -x > -9x > -1 and x < 9 -1 < x < 9

Solving an Absolute Value Inequalities

16. -12All Real Numbers!!

Solving an Absolute Value Inequalities

3x + 1 = 2 or 3x + 1 = - 2

(greatOR)

3x + 1 2 or 3x + 1 < - 2

(less thAND)

3x + 1 2 and 3x + 1 > - 2

Remember! **********

GREATOR THAN NEGATIVE◦ Infinite solutions (all real numbers)

LESS THAN NEGATIVE◦ No solutions

Remember! **********

17.

* Know it’s Great“or” >
