Write a pair of linear equations which has the unique solution `x = -1` and `y = 3`. How many such pairs can you write ?

Explanation

To write a pair of linear equations that has a unique solution of \( x = -1 \) and \( y = 3 \), we can follow these steps:

### Step 1: Identify the solution point
The unique solution given is \( (x, y) = (-1, 3) \).

### Step 2: Formulate the equations
We can start by using the point-slope form of a linear equation. The general form of a linear equation is:
\[ ax + by + c = 0 \]
