9m + 5 reverse distributive property

9m+5 since the multiplication was distributed over the addition we have to look at the inverse operation that is division distributed over addition

pick any number to divide by, let's say 10

9m/10 + 5/10 = 0.9m+0.5

now we can distribute 10 over 0.9m+0.5 and get our original answer

10 (0.9m+0.5) = 9m+5
