HELP ME THIS IS SO CONFUSING AND I DON'T UNDERSTAND ANYTHING PLZZ HELP! Simplify the expression. -7(n+3)-⅛ (8+8n)

SHOW YOUR WORK

-8n-22

Step-by-step explanation:

First you have to distribute. -7(n+3) becomes -7n-21. That's the first half done. Now let's do -1/8(8+8n) -1/8 is equal to 0.125, so we'll use that to make it simpler. 0.125x8 is simply just 1, so now we have -7n-21-1-1n. We can get rid of that one and just say n instead of 1n, it still means the same thing. Now we can combine like terms by moving the numbers around. Make sure you keep the signs in front though! -7n-n-21-1 = -8n-21-1 = -8n-22.

First, distribute the numbers.

-7(n+3)

Multiply -7 by n and -7 by 3.

-7n-21

⅛(8+8n)

Multiply ⅛ by 8 and ⅛ by 8n.

1+1n

Now place these back into the original expression.

-7n-21 - 1+1n

Now subtract the constants by the constants and the variables by the variables.

-7n - 1n = -8n

-21 - 1 = -22

Now these back into the expression now.

-8n - 22

So the expression simplified is -8n - 22.
