To solve for \( y \) in the equation \( 3x + 4y = 7 \), we can isolate \( y \):

1. Start with the original equation:
\[ 3x + 4y = 7 \]

2. Subtract \( 3x \) from both sides:
\[ 4y = 7 - 3x \]

3. Divide both sides by \( 4 \) to solve for \( y \):
\[ y = \frac{7 - 3x}{4} \]

4. This can be rewritten as:
\[ y = -\frac{3}{4}x + \frac{7}{4} \]

Thus, the correct response is:
\[ y = -\frac{3}{4}x + \frac{7}{4} \]

This corresponds to the response:
**y=−34x+74**
where the notation might have a typographical error in terms of formatting. The intention appears correct if meant to denote \( y = -\frac{3}{4}x + \frac{7}{4} \).

If rephrased clearly, the correct answer would be:
**y = -\frac{3}{4}x + \frac{7}{4}**.
