To solve the equation \(2x - y = 5\), we can express \(y\) in terms of \(x\) or vice versa. Here are a few different approaches depending on what you need:

### Solving for \(y\) in terms of \(x\):
1. Start with the given equation:
\[
2x - y = 5
\]
2. Isolate \(y\) by adding \(y\) to both sides and then subtracting 5 from both sides:
\[
2x - 5 = y
\]
3. Rewrite it as:
\[
y = 2x - 5
\]

### Solving for \(x\) in terms of \(y\):
1. Start with the given equation:
\[
2x - y = 5
\]
2. Isolate \(x\) by adding \(y\) to both sides and then dividing by 2:
\[
2x = y + 5
\]
3. Divide both sides by 2:
\[
x = \frac{y + 5}{2}
\]

### Finding specific solutions:
You can also find specific solutions by choosing values for \(x\) or \(y\) and solving for the other variable.

For example, if \(x = 3\):
1. Substitute \(x = 3\) into the equation:
\[
2(3) - y = 5
\]
2. Simplify:
\[
6 - y = 5
\]
3. Solve for \(y\):
\[
y = 6 - 5 = 1
\]
So, one solution is \((3, 1)\).

If \(y = 0\):
1. Substitute \(y = 0\) into the equation:
\[
2x - 0 = 5
\]
2. Simplify:
\[
2x = 5
\]
3. Solve for \(x\):
\[
x = \frac{5}{2} = 2.5
\]
So, another solution is \((2.5, 0)\).

### Graphical Interpretation:
The equation \(2x - y = 5\) represents a straight line in the Cartesian plane. The slope of the line is 2 (since \(y = 2x - 5\) is in slope-intercept form \(y = mx + b\) where \(m\) is the slope), and the y-intercept is -5.

You can plot the line by finding at least two points that satisfy the equation and drawing a line through them. For example, the points \((3, 1)\) and \((2.5, 0)\) found above can be used to draw the line.
