To solve the equation \( 2^x + x = 5 \), we'll use a combination of numerical and graphical methods, as there is no simple algebraic solution for this type of equation.

### Step-by-Step Approach:

1. **Graphing Method**:
   Let's define two functions:
   \[
   f(x) = 2^x + x
   \]
   and
   \[
   g(x) = 5.
   \]
   We can graph both functions and find where they intersect, which will give us the value of \( x \).

2. **Trial and Error** (Numerical Approximation):
   We can also estimate solutions by substituting values of \( x \) into the equation \( 2^x + x \) to see which value satisfies the equation \( 2^x + x = 5 \).

   - For \( x = 1 \):
     \[
     2^1 + 1 = 2 + 1 = 3.
     \]
     This is less than 5.
   - For \( x = 2 \):
     \[
     2^2 + 2 = 4 + 2 = 6.
     \]
     This is greater than 5.

   So, the solution lies between \( x = 1 \) and \( x = 2 \).

3. **Refining the Estimate**:
   We can try more precise values to narrow down the solution.

   - For \( x = 1.5 \):
     \[
     2^{1.5} + 1.5 \approx 2.828 + 1.5 = 4.328.
     \]
     This is still less than 5.
   - For \( x = 1.7 \):
     \[
     2^{1.7} + 1.7 \approx 3.249 + 1.7 = 4.949.
     \]
     This is very close to 5.
   - For \( x = 1.72 \):
     \[
     2^{1.72} + 1.72 \approx 3.287 + 1.72 = 5.007.
     \]
     This is extremely close to 5.

Thus, the approximate solution is:
\[
x \approx 1.72.
\]
