To solve the equation $X + 2 = 5$:

1. Subtract 2 from both sides to isolate $X$: $X = 5 - 2$

2. Simplify: $X = 3$

So, $X = 3$.

Would you like more details on this solution or have any questions?

Here are 5 related questions to deepen your understanding:

1. What would be the solution to $X + 7 = 10$?
2. How would you solve $X - 4 = 6$?
3. What happens if you multiply both sides of the equation $X + 2 = 5$ by 3?
4. How do you solve $2X + 5 = 11$?
5. What is the solution for $3X - 2 = 7$?

Tip: Always perform the same operation on both sides of an equation to maintain equality.
