The quotient of of a number and 2 is equal to the difference between 6 and the number . which equation represents this relationship?

The quotient of a number and 2 can be expressed as x / 2
The difference between 6 and the number can be expressed as 6 - x
therefore the answer is;
x / 2 = 6 - x

worked out it is
1/2x = -x + 6
1/2x + x = -x + 6 + x
3/2x = 6
3/2x * 2/3 = 6 * 2/3
x = 4

It will be a whole number.

Ibelieve the answer is c i worked it out three times but if my answer is wrong someone correct me
