Write 4 (8m-7n) +6 (3n-4m) in standard form by expanding and collecting like terms.. show work

4(8m-7n) + 6(3n04m)

First, I will distribute the numbers outside of parentheses to the numbers inside of the parentheses:
(32m-28n) + (18n-24m)

Next, I will take out the parentheses:
32m-28n+18n-24m

After that, I will combine all of the numbers with the m variable:
32m-28n+18m-24m
32m+18m
50m

Lastly, I will combine all of the numbers with n as a variable, treating both like negative numbers because there is a subtraction sign before them.
50m-28n-24n
-28n-24n
-52n

This ends with this expression:
50m-52n

Let me know if you need any clarifications or anything :)
