To solve the equation \(|x| + x = 5\), we need to consider two cases because of the absolute value.
Case 1: \(x \geq 0\)
In this case, \(|x| = x\). Substituting into the equation, we get:
\[
x + x = 5 \implies 2x = 5 \implies x = \frac{5}{2}
\]
Since \(\frac{5}{2} \geq 0\), this solution is valid.
Case 2: \(x < 0\)
In this case, \(|x| = -x\). Substituting into the equation, we get:
\[
-x + x = 5 \implies 0 = 5
\]
This is a contradiction, so there are no valid solutions in this case.
The only solution to the equation \(|x| + x = 5\) is: \[ x = \frac{5}{2} \]
