Answer 1

To clear the fractions we multiply both sides by the least common multiple of all the denominators.

1/2  x + 2/3 = 4

Denominators 2 and 3, so multiply both sides by [Answer]: 6

3/4 x + 1 = 5/6

Denoms 4 and 6, LCM=12  Answer: 12

6/7 x - 2/3 = 5/21

LCM(7,3,21)=21 Answer: 21

3/5 + x/2 = 9

LCM(5,2)  Answer: 10

25/4 = 6 + 1/2 x

LCM(4,2)  Answer: 4
