Question

15 more than half a number is 9

Answer 1

The number is 'N'.

Half of the number is  (1/2 N).

15 more than that is  (1/2 N + 15)

Now, you said that                    1/2 N + 15  =  9

Subtract  15  from each side:    1/2 N          =   -6

Multiply each side by  2 :                N          =  -12
