Answer: 8
Explanation:
From what I've learned, first, you move 4.4 to the left and subtract it from 6.4, leaving you with 2n-10 = 6. Then, you add 10 to the other side of the equal sign which gives you 16, so the equation should be 2n = 16. Then, you divide both sides by 2 to get n by itself, leaving you with n = 8.
