If 6/x + 2 = 5 and x ≠ 0, what is the value of x?
Answer: 2
6/x = 3, so x = 6/3 = 2.
Common wrong answers
- If you answered 3
- 3 is the value of 6/x; x itself is 6 ÷ 3 = 2.
- If you answered 18
- 18 multiplies 6 · 3; instead divide: x = 6/3.
- If you answered 0.5
- x = 1/2 gives 6/x = 12, far from 3.
