To solve this system of linear equations, let's break down each equation and see if they can be solved algebraically.

Given:
\[
4x + 7y = 1
\]
\[
-x - \frac{7}{4}y = -\frac{1}{4}
\]

### Step 1: Simplify the second equation
Multiply the entire second equation by 4 to eliminate the fraction:
\[
-4x - 7y = -1
\]

### Step 2: Compare the equations
We now have:
1. \(4x + 7y = 1\)
2. \(-4x - 7y = -1\)

Add these two equations together:
\[
(4x + 7y) + (-4x - 7y) = 1 + (-1)
\]
\[
0 = 0
\]

This result indicates that the system is dependent, meaning there are infinitely many solutions.

### Step 3: Express \( y \) in terms of \( x \)
Since the system is dependent, we can solve one of the equations for \( y \) in terms of \( x \).

Using the first equation:
\[
4x + 7y = 1
\]
Solve for \( y \):
\[
7y = 1 - 4x
\]
\[
y = \frac{1 - 4x}{7}
\]

### Solution
The solution set for this system is:
\[
y = \frac{1 - 4x}{7}
\]
where \( x \) can be any real number.
