Algebra practice question

Answer: 8

Common denominator 4: 2x/4 + x/4 = 3x/4 = 6. Multiply by 4/3: x = 8. Check: 4 + 2 = 6.

Common wrong answers

If you answered 4

4 comes from x/2 + x/4 = 6 with x/4 dropped (x/2 = 6 → 12) or halved wrongly; 4/2 + 4/4 = 3, not 6.

If you answered 12

12 solves x/2 = 6 alone, ignoring the x/4 term.

If you answered 24

24 solves x/4 = 6 alone, ignoring the x/2 term.
