Let's solve the equation step by step:

Given equation:

$x - 5 = 4$

To solve for $x$, add 5 to both sides of the equation:

$x - 5 + 5 = 4 + 5$

This simplifies to:

$x = 9$

Conclusion:

The equation has one solution because we have found a specific value of $x$ that satisfies the equation.

Verification:

To verify, substitute $x = 9$ back into the original equation:

$9 - 5 = 4$

This is true, so the solution is correct. The value $x = 9$ supports the conclusion that the equation has one solution.

Answer:

• The equation has one solution.
• The value of $x$ that supports this conclusion is $x = 9$.
