x-4(8-4x) =
first multiply the -4 by the terms in brackets
x - 32 + 16x =
combine the x terms
17x - 32

X - 4(8 - 4X)
X - 32 + 16X
-32 + 17X
Notice the - sign before the 4. That distributes when you expand 4(8 - 4X), negative times positive you get the - 32. Now -4 times -4X you get +16X

x-4(8-4x)
Reorder the polynomial 8-4x alphabetically from left to right, starting with the highest order term.
x-4(-4x+8)
Multiply -4 by each term inside the parenthesis.
x+(16x-32)
Since x and 16x are like terms, add 16x to x to get 17x.
17x-32

X-4(8-4x).
= X-32 +16x
If X = x, then we have 17x-32
