Question 15234
Let x= the number.
Then we have to make an equation based on what we are given.
So the number halved would be represented by{{{x/2}}}.
To this add 9 so {{{x/2 + 9}}}
Let this then = 63. So we get:
{{{x/2 + 9=63}}}
Now rearrange the equation
Subtract 9 from both sides to give {{{x/2=54}}}
Then multiply both sides by 2 which gives:
x=108
so the number is 108
