Group our variables 13c and 18c subtract 18c from both sides 13c + 100 - 18c = 18c - 18c
Cancel 18c on the right side:
-5c + 100 = 0
Group constants
Group our constants 100 and 0. subtract 100 from both sides -5c + 100 - 100 = 0 - 100
Cancel 100 on the left side:
-5c = -100
Divide each side of the equation by -5
-5c
-5
=
-100
-5
c = 20
c = 20
What is the Answer?
c = 20
