Answer:
a = 3.75
Step-by-step explanation:
First distribute the -3 to (a - 6), which gives you the equation, 19a - 3a + 18 = 78. Then subtract the 3a from 19a, which gives you 16a + 18 = 78. Then subtract 18 from both sides and you get 16a = 60. Divide 60 by 16 and you get 3.75 as your a.

<h3>What is addition?</h3>
Combining items and counting them as a single, large group is done through addition.
Given that, Noelia has 144 role-playing cards.
