11n + 5 = 13n Subtract 11n from both sides
5 = 2n Divide both sides by 2
[tex] \frac{5}{2} [/tex] = n Switch the sides to make it easier to read
n = [tex] \frac{5}{2} [/tex]
Check your answer:
11n + 5 = 13n Substitute n for [tex] \frac{5}{2} [/tex]
11([tex] \frac{5}{2} [/tex]) + 5 = 13([tex] \frac{5}{2} [/tex]) Simplify
[tex] \frac{55}{2} [/tex] + [tex] \frac{10}{2} [/tex] = [tex] \frac{65}{2} [/tex] Add
[tex] \frac{65}{2} [/tex] = [tex] \frac{65}{2} [/tex]
