AlgebraEasyMissing value in a table of solutions
Algebra practice question
Each pair (x, y) in the table satisfies 3x + 4y = 24. x | y 0 | 6 4 | 3 8 | ? What is the missing value of y?
Answer: 0
3(8) + 4y = 24 gives 4y = 0, so y = 0.
Common wrong answers
- If you answered 2
- 2 comes from 4y = 8.
- If you answered 3
- 3 copies the row above.
- If you answered -3
- −3 continues the pattern of subtracting 3 but oversteps; 3(8) = 24 leaves nothing for y.
