Solve for y: 2y - 4 = 10.

y = 5
y = 7
y = 8
y = 10

The correct answer is: y = 7

To solve the equation 2y - 4 = 10, the goal is to isolate the variable y. First, add 4 to both sides of the equation. This gives you: 2y - 4 + 4 = 10 + 4, which simplifies to: 2y = 14. Next, to solve for y, divide both sides of the equation by 2: 2y/2 = 14/2, resulting in: y = 7. This means the correct answer is y = 7. By following these steps, you systematically isolate y and reach the correct solution.
