First, substitute 4 for x and you have
2*4*4
2*4*4=2*16=32
so the answer is 32!
(when you see something like 2x or 7y or any other number when there is a variable and a number but no sign, it is multiplied.)

If there is no sign between 2 and x, then 2 is multiplied by x.
Now x = 4
So, (2*4)*4
= 8 times 4
=32
Simple : )

If x=4 then 2x=8 so 2x*4=32!
