The given equation is:

$2x + y = 5$

There are several ways to work with this equation depending on what you need. For instance, we can solve for $y$ in terms of $x$, or for $x$ in terms of $y$. Let me solve for $y$ in terms of $x$:

$y = 5 - 2x$

This is the equation of a straight line in slope-intercept form, where the slope is $-2$ and the y-intercept is $5$.

Would you like further details or specific questions on this?

Here are five related questions:

1. What is the slope of the line represented by $2x + y = 5$?
2. How do we find the x- and y-intercepts of this line?
3. What is the solution to this equation if $x = 1$?
4. Can you plot this equation on a graph and find its key features?
5. How would you solve for $x$ if $y = 3$?

Tip: For any linear equation in the form $ax + by = c$, rearranging it into slope-intercept form $y = mx + b$ helps in quickly identifying the slope and intercept.
