$- 43 + 15 m$ $-43+15m$

Use the order of operations:

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

So:

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

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

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

Then, we need to combine like terms.

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

$- 43 + 6 m + 9 m$ $-43 + 6m + 9m$

$- 43 + 15 m$ $-43 + 15m$

How do you simplify -9+4(m-7)-6+2m+9m −9+4(m−7)−6+2m+9m-9+4(m-7)-6+2m+9m ?
