Answer 1

To simplify the expression \(28x + 310y - 58x + 410y\), we will combine like terms for \(x\) and \(y\).

1. Combine the \(x\) terms: \[ 28x - 58x = -30x \]

2. Combine the \(y\) terms: \[ 310y + 410y = 720y \]

Putting it all together, we have: \[ -30x + 720y \]

Therefore, the simplified expression is: \[ -30x + 720y \]

It seems that the available responses do not include this exact answer, suggesting a potential error. But based on the calculations provided, the correct simplification is \(-30x + 720y\).
