Hey there!
8 - n = -4
-n + 8 = -4
SUBTRACT 8 to BOTH SIDES
-n + 8 - 8 = -4 - 8
CANCEL out: 8 - 8 because that gives you 0
KEEP: -4 - 8 because that helps solve for your n-value
-4 - 8 = -12
NEW EQUATION: -n = -12
(We have a variable by itself it’s understood as a(n) invisible 1)
DIVIDE -1 to BOTH SIDES
-n/-1 = -12/-1
CANCEL out: -1/-1 because that gives you 1
KEEP: -12/-1 because that gives you the value of n
-12/-1 = 12
Answer: n = 12
Good luck on your assignment and enjoy your day!
