multiply by 4 through 5x-4w
so -2w + 20x - 16w + 8
so 20x -18w + 8
simple

Use common mathematics you may subtract 2w from each and each side 4w + 8 - 2w = 2w + 7 - 2w Rearranging and grouping (4w - 2w) + 8 = (2w - 2w) + 7 2w + 8 = 7 you may now subtract 8 from each and each side 2w + 8 - 8 = 7 - 8 2w = -a million Now divide each and each side by ability of two 2w/2 = -a million/2 w = -a million/2 examine the answer by ability of substituting -a million/2 for w: 4 * -a million/2 + 8 = -2 + 8 = 6 2 *-a million/2 + 7 = -a million + 7 = 6 6 = 6 so w does certainly equivalent -a million/2 With practice you'll detect the thanks to consolidate the steps, yet continuously examine your answer.

to begin, you need to distribute the 4 to 5x and -4w
so it would look like:
-2w + 20x - 16w + 8
then you combine like terms:
-2w & -16w
so it would look like
20x - 18w + 8 which is your answer
(you cannot simplify any more because they aren't like terms)

-2w+4(5x-4w)+8
-2w+20x-16w+8
-18w+20x+8
(I think that's right!)
I've shown working out
