To solve the equation (4y - 5 = 3), the goal is to isolate (y). Begin by adding 5 to both sides of the equation to eliminate the -5:

[4y - 5 + 5 = 3 + 5]

This simplifies to:

[4y = 8]

Next, to find (y), divide both sides by 4:

[y = \frac{8}{4}]

This results in:

[y = 2]

Thus, the value of (y) is 2. This option is correct because it successfully satisfies the original equation when substituted back in. Checking:

Substituting (y = 2) back into the original equation gives:

[4(2) - 5 = 3]

Which simplifies to:

[8 - 5 = 3]

This verifies that (y = 2) is indeed the correct solution. Other options do not satisfy the equation when checked in this manner.
