Simplify the expression.

9r − 2s − 4r − 3s

5r - 5s

To simplify the expression 9r - 2s - 4r - 3s, we can combine like terms:

Combining the "r" terms, we have:
9r - 4r = 5r

Combining the "s" terms, we have:
-2s - 3s = -5s

Therefore, the simplified expression is:
5r - 5s

To simplify the expression 9r - 2s - 4r - 3s, we need to combine the like terms.

First, combine the terms with the variable "r", which are 9r and -4r. To combine them, we subtract the coefficients: 9r - 4r = 5r.

Next, combine the terms with the variable "s", which are -2s and -3s. To combine them, we subtract the coefficients: -2s - 3s = -5s.

So the simplified expression is 5r - 5s.
