To answer the question we first need to understand what X is.
X is an unknown, meaning it's a symbol that represents another number, an unknown one, that could be there in its place.
Usually in exercises we'll need to calculate and discover what X is appropriate for each exercise,
but in this case the result is given to us: X=8
Therefore, we can substitute (plug in) the value 8 everywhere X appears in the exercise.
So we get:
5*8-6
40-6
34
