Advanced Math practice question

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.
