4

5

To find the value of y in the equation 4y - 8 = 12, we can follow these steps:

1. **Add 8 to both sides**: This helps isolate the term involving y.

\[

4y - 8 + 8 = 12 + 8

\]

This simplifies to:

\[

4y = 20

\]

2. **Divide both sides by 4**: This step will solve for y.

\[

y = \frac{20}{4}

\]

This gives us:

\[

y = 5

\]

Thus, the correct value of y is 5. In the context of the choices provided, this means the answer aligns with the value 5, confirming that it is indeed the solution to the equation.

Each step in the isolation process effectively reduces the complexity of the equation, demonstrating the importance of maintaining balance when solving algebraic equations. This method reinforces understanding and provides a clear approach to isolating variables.
