Advanced Math practice question

Answer: 7

Write 2/x as 4/(2x); then 4/(2x) + 3/(2x) = 7/(2x), so a = 7.

Common wrong answers

If you answered 4

4 is only the converted first numerator; add the 3.

If you answered 5

The numerators cannot be added until the denominators match: 2/x = 4/(2x).

If you answered 6

Check: 2/x converts to 4/(2x), not 3/(2x).
