Algebra practice question
The equations 4x = 20 and x = 5 have the same solution. Which operation turns the first equation into the second?
- A. Dividing both sides by 4Correct
- B. Subtracting 4 from both sides
- C. Multiplying both sides by 4
- D. Adding 5 to both sides
Answer: A. Dividing both sides by 4
4x ÷ 4 = x and 20 ÷ 4 = 5.
Why the other answers are wrong
- B. Subtracting 4 from both sides
- Subtracting 4 gives 4x − 4 = 16.
- C. Multiplying both sides by 4
- Multiplying gives 16x = 80.
- D. Adding 5 to both sides
- Adding 5 gives 4x + 5 = 25.
