Answer #1

Given : Equation

9c + 19 d - 4c + 5d = ?

When collecting terms the sign at the front of the number tell us  wether we have to add or substract them.

Firstly rewrite the equation , so that the like terms are together.

9c - 4c + 19d +5d

Now substract and add appropriately.

9c - 4c = 5c

19d + 5d = 24 d

Therefore final answer is :

5c + 24 d
