As long as  b5   means  b times 5   then...

 

1465  =  b5 + 5

                               we can just rewrite  b5  as  5b

1465  =  5b + 5

                               Subtract  5  from both sides of the equation

1460  =  5b

                               Divide both sides of the equation by  5

292  =  b

                               That is the same as...

b  =  292
