What is the missing number?

- 2 = 4

OK, the solution is six, right? as a result of sixa pair of = four. Easy stuff.

Well, in pure mathematics we do not use blank boxes, we have a tendency to use a letter (usually associate degree x or y, however any letter is fine). thus we have a tendency to write:
x - a pair of = four

It is extremely that straightforward. The letter (in this case associate degree x) simply means that "we do not know this yet", and is usually known as the unknown or the variable.

And {when we have a tendency to|once we|after we} solve it we write:
x = 6
