Answer:
5/3 or 1.6666...
Step-by-step explanation:
9 - 2n = 4(n - 3) (distribute parentheses first i.e PEDMAS)
9 - 2n = 4(n) - 4(3)
9 - 2n = 4n - 12 (subtract 9 from both sides)
- 2n = 4n - 1 - 9
- 2n = 4n - 10 (subtract 4n from both sides)
- 2n -4n = -10
-6n = -10 (divide both sides by -6)
n = -10 / -6 = 10/6 = 5/3
