1
Solve the following equations for x: 1) 2) 3) 4) 5) 6)

2
1.Distribute if there are parenthesis. 2. Combine like terms. 3. Move variable on right side to left side (add or subtract). 4. Move constants on left side to right side (add or subtract). 5. Get rid of coefficient or denominator (divide or multiply). 6. IF, you multiply or divide by negative number in Step 5, flip the inequality symbol.

3
Inequality Signs When graphing the number use a … Closed Circle OPEN Circle Less than or equal to: Less than: Greater than or equal to: Greater than:

4
Inequality Signs Read left to right: a < b a is less than b a < b a is less than or equal to b a > b a is greater than b a > b a is greater than or equal to b

5
Determine whether the given number is a solution of the inequality. 1.) x + 3 < 6 ; 5 2.) 2x – 3 > -3 ; 1 3.) 4x – 1 3x + 2 ; 3 8 < 6 False, not a solution 2 – 3 > -3 True, it is a solution -1 > -3 12 – 1 9 + 2 True, it is a solution 11 11

6
Graph using a number line Opened Circle Shade to the left 0 1 2 3 4 5 Closed Circle Shade to the right -5 -4 -3 -2 -1

7
6. x + 4 > 7 -4 -4 x > 3 Solve. Then graph.

8
Try These Solve then graph.
