Question

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

Answer 1

#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.

Answer 2

how do you do number 2. with a mixed number like multiply it by 10

Answer 3

-2 3/10 = -23/10
