Let x= the number.
Then we have to make an equation based on what we are given.
So the number halved would be represented byx%2F2.
To this add 9 so x%2F2+%2B+9
Let this then = 63. So we get:
x%2F2+%2B+9=63
Now rearrange the equation
Subtract 9 from both sides to give x%2F2=54
Then multiply both sides by 2 which gives:
x=108
so the number is 108
