Answer:
c = 80/9 or c = 8.888...
Step-by-step explanation:
<u>Step 1: Combine like terms
</u>
100 - 1 - 9c = 19
99 - 9c = 19
<u>Step 2: Subtract 99 from both sides
</u>
99 - 9c - 99 = 19 - 99
-9c = -80
<u>Step 3: Divide both sides by -9
</u>
-9c / -9 = -80 / -9
c = 80/9 or c = 8.888...
Answer: c = 80/9 or c = 8.888...
