Solve: 3(2y - 1) - 5y = 2(y + 1) - 2(y + 3).
Ay=1
By=-4
Cy=-1
Dy=4
Answer & Solution
Correct answer: C. y=-1
1. Distribute and combine on the left: 3(2y - 1) - 5y becomes 6y - 3 - 5y, which simplifies to y - 3.
2. Distribute and combine on the right: 2(y + 1) - 2(y + 3) becomes 2y + 2 - 2y - 6, which simplifies to -4.
3. The equation is now y - 3 = -4.
4. Add 3 to both sides to get y = -1, and checking confirms both sides equal -4 when y is -1.
