Ay=7
By=5
Cy=3
Dy=42
Answer & Solution
Correct answer: A. y=7
1. Find the LCD of the fractions, which is 6.
2. Multiply every term on both sides by 6 to clear the fractions: y minus 2 equals 5.
3. Add 2 to both sides to get y equals 7.
4. Check: one-sixth of 7, minus one-third, equals seven-sixths minus two-sixths, which equals five-sixths.
