9{[4(m-5)+19] - [2(5m-2) +1]} ... Start with the given expression.


9{[4m-20+19] - [10m-4 +1]} ... Distribute


9{[4m-1] - [10m-3]} ... Combine like terms.


9{4m - 1 - 10m + 3} ... Distribute the negative.


9{-6m + 2} ... Combine like terms.


-54m + 18 ... Distribute.



==========================================
Answer:

So
9{[4(m-5)+19] - [2(5m-2) +1]} = -54m + 18
