Combine any like terms in the expression. If there are no like terms, rewrite the expression.

To combine the like terms in the expression \(5rs + 3rs - 7rs + 8pq\), we first identify the like terms, which in this case are all the terms that contain \(rs\).

1. Combine the coefficients of \(rs\):

   • \(5rs + 3rs - 7rs = (5 + 3 - 7)rs = 1rs = rs\)

2. The term \(8pq\) remains unchanged since it does not have any like terms.

Putting it all together, the simplified expression is: \[ rs + 8pq \]
