#-43+15m#

Use the order of operations:

P arentheses
E xponents
M ultiplication
D ivison
A ddition
S ubtraction

So:

#-9 + 4(m-7)-6+2m+9m#

First lets distribute the #4# across the values inside the parentheses.

#-9 + 4m - 28-6+2m+9m#

Then, we need to combine like terms.

#-9+4m-28-6+2m+9m#

#-43 + 6m + 9m#

#-43 + 15m#
