Solve: \(\frac{y + 1}{2} - \frac{2y - 1}{3}\) = 4
- A. y = 19
- B. y = -19
- C. y = -29
- D. y = 29
Correct Answer: B. y = -19
Explanation
\(\frac{y + 1}{2} - \frac{2y - 1}{3}\) = \(\frac{4}{1}\)
- \(\frac{3(y + 1) - 2(2y - 1)}{6} = \frac{4}{1}\)
3y + 3 - 4y + 2 = 24
- y + 5 = 24
- y = 24 - 5 = 19
y = - 19
