Worksheet Overview

QUESTION 1 of 10

This worksheet is about solving two inequalities.

 

Example

Solve the inequalities.

x ≥ -12 and 2x + 6 ≤ -6

 

Answer

x ≥ -12 is the same as saying -12 ≤ x

 

To solve 2x + 6 ≤ -6

we subtract 6 from both sides to get:

2x ≤ -12

and halve both sides to get:

x ≤ -6

 

Putting the two solutions together we get:

 

-12 ≤ x ≤ -6

Solve the inequalities.

x ≤ 8 and 4x -1 > 7

10 ≤ x < 13

2 < x ≤ 8

Solve the inequalities.

x > -7 and 4x + 13 < -3

10 ≤x < 13
