Answer 3

It looks like you've provided an equation with some operations. Let's break it down step by step and solve for $x$ and $y$.

The equation you've given is:

$280(x - 10) = 714y + 13 - 7y = 153$

However, there seems to be a mistake in your equation. It appears that you've used multiple equal signs, which isn't valid in this context. Please double-check and provide the correct equation.
