🎯 WALT: Form and solve one-step linear equations

Remember: Use inverse operations to solve equations. Always check your answer!

1. Solve: x + 8 = 15

2. Solve: m - 6 = 11

3. Solve: 4y = 28

4. Solve: n ÷ 5 = 9

5. Which operation would you use to solve 3t = 21?

Add 3 to both sides

Subtract 3 from both sides

Multiply both sides by 3

Divide both sides by 3

Steps: 1) Write the equation 2) Solve using inverse operations 3) Check your answer
