The Deep Dive
To solve the equation \( 4x + 7y = 28 \) for \( y \), we start by isolating \( y \). 1. Subtract \( 4x \) from both sides: \[ 7y = 28 - 4x \] 2. Now, divide both sides by \( 7 \): \[ y = \frac{28 - 4x}{7} \] 3. We can simplify this: \[ y = 4 - \frac{4}{7}x \] Thus, the simplified expression for \( y \) is: \[ y = 4 - \frac{4}{7}x \]
