X+4-5=3

To solve the equation \( X + 4 - 5 = 3 \), start by simplifying the left side:

1. Combine the constants: \( 4 - 5 = -1 \).
2. Rewrite the equation: \( X - 1 = 3 \).

Next, add 1 to both sides to isolate \( X \):

\[ X - 1 + 1 = 3 + 1 \]

This simplifies to:

\[ X = 4 \]

So, the solution is \( X = 4 \).
