Group our variables 7n and 3n subtract 3n from both sides 7n + 25 - 3n = 3n + 93 - 3n
Cancel 3n on the right side:
4n + 25 = 93
Group constants
Group our constants 25 and 93. subtract 25 from both sides 4n + 25 - 25 = 93 - 25
Cancel 25 on the left side:
4n = 68
Divide each side of the equation by 4
4n
4
=
68
4
n = 17
n = 17
What is the Answer?
n = 17
