xy-(xy+10x+14y-140)=xy+4

To solve the equation \(xy - (xy + 10x + 14y - 140) = xy + 4\), let's simplify the left side first.

1. Distribute the negative sign on the left side: \[ xy - xy - 10x - 14y + 140 = xy + 4 \]

2. The \(xy\) terms on the left cancel out: \[ -10x - 14y + 140 = xy + 4 \]

3. Rearranging the equation gives: \[ -10x - 14y + 140 - 4 = xy \] \[ -10x - 14y + 136 = xy \]

4. This can also be rearranged as: \[ xy + 10x + 14y - 136 = 0 \]

Now, this equation can be treated as a polynomial in two variables \(x\) and \(y\). If you need a specific solution or further analysis (like finding points or solutions for specific values of \(x\) or \(y\)), please let me know!
