how do you solve these problems?

1.2x/3 + 1/3 - x/8= 2/3

2. 3n + 9/10 + n/5= -2 3/10

3. 3k/4 - 28 - 2k/3 = 37

#1: Multiply both sides by a common denominator, in this case 24.

So you'll get

24* (2x/3 + 1/3 - x/8) = 24* (2/3 )

16x + 8 - 3x = 16

13x = 8

x = 8/13

#2: Multiply both sides by 10

#3: Multiply both sides by 12.
