Solve the inequality and graph on a number line:
14x - 3 ≤ -3

• x ≤ 0
•  x ≤ 2
• x > 0
• x ≥ -2

Solve the inequality and graph on a number line:
12 - 2x < 16

• x < -2
• x ≤ 0
• x > -2
• x ≤ 6

• x= 12
• x= -12
• x= -22
• x= 22

• x= 1
• x= -1
• x= 2
• x= -2

Solve for x:

• x = 20
• x = 7
• x = 10
• x = 3

Solve the inequality and graph on a number line:
14x - 3 ≤ -3

• x ≤ 0
•  x ≤ 2
• x > 0
• x ≥ -2

Match the graph with its inequality.

• a > 11
