Por favor son problemas de fracciones

3/2 + 4/5 + 6/x =4

×/4 - 9/3 + 1/5=7

4/5 ÷ x/3= 9

Answer 1

*3/2 + 4/5 + 6/x =4

23/10 + 6/x = 4

6/x = 4 - 23/10

6/x = 17/10

60 = 17x

17x = 60

x = 60/17

*×/4 - 9/3 + 1/5=7

x/4 - 14/5 = 7

5x - 56 = 140

5x = 140 + 56

5x = 196

x = 196/5

*4/5 ÷ x/3= 9

4/5 x 3/x = 9

12/5x = 9

12 = 45x

45x = 12

x = 12/45

x = 4/15
