For any number a, b and c, If a = b then 

                  (Divide each side by 5 )

                      (Cancel common terms)

n = 24                           (Divide:)

\ \

Verify:

To check the solution, substitute n = 24 in original equation. 

5n = 1205(24) = 120      

120 = 1250                 (Multiply: 5(24) = 120)

Compare the values, the equation is true. The solution is n = 24. \ \
