1. Warm ups Solve for x. x + 14 = 16 -11 + x = 4 5x – 3 = 4x + 2

2. 7-1 Solving Inequalities using Addition and Subtraction
Objective: To solve inequalities by adding or subtracting.
Standard 5.0

3. Inequalities – not equal
is at least
is at most

4. Examples 5.

5. Graphing – letter always on left
Shade on number line – the arrow will tell you what direction to shade
< open circle to left
x < 7
> open circle to right
x > -2 7 -2

6. Graphing (continued) < closed circle to left
x < -13
> closed circle to right
x > 18
-13 18

7. 4 Things you need: TOO: y > 28 r<31 Circle Number and zero
Shaded or open circle
Arrow (shading)
TOO:
y > r<31

8. Translate, solve, and graph
Three times a number is more than the difference of twice that number and three.
