[tex]\frac{b}{5}=2[/tex]
If we replace with 10:
[tex]\frac{10}{5}=2[/tex][tex]2=2[/tex]
10 is a solution.
Let's try with 11:
[tex]\frac{11}{5}=2[/tex][tex]2.2\ne2[/tex]
11 is not a solution.
WIth 12:
[tex]\frac{12}{5}=2[/tex][tex]2.4\ne2[/tex]
12 is not a solution
WIth 13
[tex]\frac{13}{5}=2[/tex][tex]2.6\ne2[/tex]
13 is not a solution.
Therefore, the solution to this equation is 10
