Answer 1

n = 4

Explanation:

-170=-7(8n-7) +5

-170=-56n+49+5

-170=-56n+54

-170+56n=54

56n=170+54

56n= 224

n=4

Answer 2

n=4

Explanation:

Let's get rid of the parenthesis first. We're left with -170=-56n+49+5. Let's move all of the numbers together so that the variable is separated from the numbers. Now we have 56n=224 using inverse operations. If we divide both sides by 56, we're left with n=4.

Hope this helped!
