Two Step Equations

3c + 5 = 23

• c = 3
• c = 6
• c = 7
• c = 18

4x + 7 = 23

• x = 16
• x = 4
• x = 9
• x = 12

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 k:
3k + 5 = 23

• k = 4
• k = 5
• k = 6
• k = 7

6p - 5 =13

• 12
• 15
• 3
• -3

4x + 7 = 23

• x = 16
• x = 4
• x = 9
• x = 12

The objective when solving an equation is to....

• isolate the variable.
• check the solution.
• guess and check.
• hope you get the right answer.

-4x+1=21

• x=120
• x=5
• x=30
• x=-5

The steps in solving 5b - 6 = 24 are: 

• Add 6 to both sides and divide both sides by 5
• Add 6 to both sides and multiply both sides by 5
• Subtract 6 from both sides then multiply both sides by 5
• Subtract 6 from both sides then divide both sides by 5

15 = 2a + 7

• 2
• 4
• 12
• 14
