The problem in the image asks to solve a differential equation using the Laplace transform method. The equation is:

\[
x''(t) - x'(t) = e^t
\]
with initial conditions:
\[
x(0) = 0, \quad x'(0) = 1
\]

### Solution Using Laplace Transform:

1. **Take the Laplace transform of both sides**:
   - The Laplace transform of \(x''(t)\) is \(s^2 X(s) - s x(0) - x'(0)\).
   - The Laplace transform of \(x'(t)\) is \(s X(s) - x(0)\).
   - The Laplace transform of \(e^t\) is \(\frac{1}{s-1}\).

   So, applying the Laplace transform to the given equation:
   \[
   \mathcal{L}\{x''(t) - x'(t)\} = \mathcal{L}\{e^t\}
   \]
   This gives:
   \[
   (s^2 X(s) - s x(0) - x'(0)) - (s X(s) - x(0)) = \frac{1}{s-1}
   \]

2. **Substitute the initial conditions**:
   Since \(x(0) = 0\) and \(x'(0) = 1\), we substitute these values:
   \[
   s^2 X(s) - 1 - s X(s) = \frac{1}{s-1}
   \]
   Simplify:
   \[
   X(s)(s^2 - s) = \frac{1}{s-1} + 1
   \]
   \[
   X(s)(s^2 - s) = \frac{s}{s-1}
   \]

3. **Solve for \(X(s)\)**:
   \[
   X(s) = \frac{s}{(s-1)(s^2 - s)}
   \]

4. **Simplify the expression**:
   Factor the denominator:
   \[
   X(s) = \frac{s}{(s-1)s(s-1)} = \frac{1}{s-1}
   \]

5. **Inverse Laplace transform**:
   The inverse Laplace transform of \(\frac{1}{s-1}\) is \(e^t\).

Therefore, the solution to the differential equation is:
\[
x(t) = e^t
\]

**Tip:** Always check the form of the differential equation and initial conditions before taking the Laplace transform to avoid mistakes!
