To solve the equation \( 3 = 2x + b \), we can express \( b \) in terms of \( x \):

\[
b = 3 - 2x
\]

This equation shows that \( b \) is dependent on the value of \( x \). Without further information or a specific value for \( x \), \( b \) remains a variable.

Would you like more details on solving this or a related problem?

Here are 5 related questions:
1. What happens if you substitute \( x = 0 \) in the equation?
2. Can you solve for \( x \) if \( b \) is known?
3. How does the graph of \( y = 2x + b \) change as \( b \) changes?
4. What is the slope of the line represented by \( y = 2x + b \)?
5. How would you solve this equation if it was part of a system of equations?

**Tip**: To solve for unknowns, isolate variables using inverse operations like addition, subtraction, multiplication, or division.
