Heya! here is your answer - -

8 + 19t - 6t + 8 - 13t

= 8 + 8 - 19t + 19t

= 16

Hi there! The answer is 8 + 13t

We can combine 19t and - 6t. When we subtract these from each other, we get the following: 19t - 6t = 13t

(If you don't understand this, you can see it as a story - - You have 19 apples (19a) and subtract 6 apples (6a), what's left? Answer 13t)

We can't add the seperate number (8) to this 13t, so it rests "free-standing"

Hence, 8 + 13t
