Worked examples
Real problems from the practice worksheets, solved one step at a time.
Example 1
Solve: 5x + 9 = 34
- Subtract 9 from both sides: 5x = 34 โ 9 = 25.
- Divide both sides by 5: x = 25 รท 5 = 5.
- Check: 5 ร 5 + 9 = 34 โ So x = 5.
Answer: 5
Example 2
Solve: 4x + 8 = 24
- Subtract 8 from both sides: 4x = 24 โ 8 = 16.
- Divide both sides by 4: x = 16 รท 4 = 4.
- Check: 4 ร 4 + 8 = 24 โ So x = 4.
Answer: 4
Example 3
Solve: 3x + 14 = 41
- Subtract 14 from both sides: 3x = 41 โ 14 = 27.
- Divide both sides by 3: x = 27 รท 3 = 9.
- Check: 3 ร 9 + 14 = 41 โ So x = 9.
Answer: 9
