For the system of equations to have an infinite number of solutions, the second equation must be a multiple of the first equation or can be expressed in the same form.

Given the first equation:

\[ 3x + 4y = 1 \]

Let's express \( y \) in terms of \( x \) for this equation. To do this, we can solve for \( y \):

  1. Rearranging the equation: \[ 4y = 1 - 3x \]
  2. Dividing by 4: \[ y = \frac{1 - 3x}{4} \]

Now, to create a second equation that will give us an infinite number of solutions, we could multiply the entire first equation by a non-zero constant \( k \). For example, if we let \( k = 1 \), we would have:

\[ y = \frac{1 - 3x}{4} \Rightarrow \text{(as our second equation)} \]

Alternatively, we could also write it as:

\[ y = \frac{1}{4} - \frac{3}{4}x \]

Thus, the complete statement is:

The system of equations \( 3x + 4y = 1 \) and \( y = \frac{1 - 3x}{4} \) has an infinite number of solutions.
