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!
