Two Step Equations

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

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

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.

Identify the steps to solve for b

• 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

Solve for x

4x + 7 = 23

• x = 16

• x = 4
