What is the number?
Answer provided by our tutors
Let 'x' represent the number we are looking for, than we have:
2*x - x/2 = 108
Let's multiply both sides of the equation by 2
2*2*x - (x/2)*2 = 2*108
4*x - x = 216
3*x = 216
x = 216 / 3
x = 72
Indeed,
2*72 - 72/2 = 144 - 36 = 108
The number that we are looking for is 72.
