Equations and Inequalities

What is the first step to solve this equation:
11 - 3x = 44

• Add 3 to both sides
• Subtract 11 from both sides
• Add 11 to both sides
• Divide 3 on both sides.

Solve for x:
52 = -5x - 3

• x = 11
• x = -11
• x = 275
• x = -275

4 = 2(x + 3)

• 1/2
• 7/2
• -1
• 5

c/2 =  -14

• c = -7
• c = -7
• c = -28
• c =  28

Which equation has x =2 as a solution?

• 3 + x = 10
• 11 + x = 13
• 4x = 32
• 5x =25

Which graph matches the inequality
-2 ≥ n?

• A
• B
• C
• D

Write an inequality for Graph 3.

• x ≤ -2 AND x > 5
• x ≤ -2 OR x > 5
• x ≥ -2 OR x < 5
• -2 ≤ x < 5

Solve for k. 

7k – 2 ≥ -9
