Simplify by combining like terms.

9m + 5m - 4

14m -4

thank you

9m+(-5m)

You're welcome.

To simplify by combining like terms, we need to group together the terms that have the same variable and combine their coefficients.

In this case, we have two terms with the variable "m": 9m and 5m. We can combine these two terms by adding their coefficients.

9m + 5m can be rewritten as (9 + 5)m or 14m.

So, simplifying 9m + 5m - 4 gives us 14m - 4.
