We are tasked with solving a simultaneous equation. The given system is:

\[
\frac{7}{2x + 1} + \frac{13}{y + 2} = 27 \tag{1}
\]
\[
\frac{13}{2x + 1} + \frac{7}{y + 2} = 33 \tag{2}
\]

### To solve these equations, we can follow these steps:
1. **Set common terms:**
   Define new variables for the denominators:
   - Let \( A = \frac{1}{2x + 1} \)
   - Let \( B = \frac{1}{y + 2} \)

   The system becomes:
   \[
   7A + 13B = 27 \tag{3}
   \]
   \[
   13A + 7B = 33 \tag{4}
   \]

2. **Solve the linear system:**
   We'll now solve these two equations simultaneously.

Let's work through this step-by-step. I'll calculate the solutions.The solution to the system of equations is:

\[
A = 2 \quad \text{and} \quad B = 1
\]

### Now, recall the definitions of \( A \) and \( B \):
- \( A = \frac{1}{2x + 1} \)
- \( B = \frac{1}{y + 2} \)

Substituting the values of \( A \) and \( B \) back into these equations:

\[
\frac{1}{2x + 1} = 2 \quad \Rightarrow \quad 2x + 1 = \frac{1}{2} \quad \Rightarrow \quad x = -\frac{1}{4}
\]

\[
\frac{1}{y + 2} = 1 \quad \Rightarrow \quad y + 2 = 1 \quad \Rightarrow \quad y = -1
\]

### Therefore, the solution to the original simultaneous equations is:
\[
x = -\frac{1}{4} \quad \text{and} \quad y = -1
\]

**Tip:** When solving simultaneous equations, always look for patterns that allow simplifications, such as common denominators or variable elimination.

Solve the simultaneous equation: 7/(2x + 1) + 13/(y + 2) = 27 and 13/(2x + 1) + 7/(y + 2) = 33.
