Question

How to solve 11n+5=13n

Answer 1

The answer is 5/2 (fraction)

Answer 2

11n + 5 = 13n   Subtract 11n from both sides
         5 = 2n    Divide both sides by 2
         $\frac{5}{2}$ = n     Switch the sides to make it easier to read
         n = $\frac{5}{2}$

Check your answer:

11n + 5 = 13n   Substitute n for $\frac{5}{2}$
11($\frac{5}{2}$) + 5 = 13($\frac{5}{2}$)   Simplify
$\frac{55}{2}$ + $\frac{10}{2}$ = $\frac{65}{2}$   Add
$\frac{65}{2}$ = $\frac{65}{2}$
