Question

2X/5 + 15X - 1/20 = 1/3 AJUDAAAAAAAAA

Answer 1

2X/5 + 15X - 1/20 = 1/3

2x+15x=1/3 .5.20.1

17x=100/3

17x.3=100

51x=100

x=100/51

x=5100

Answer 2

Resolução:

2x/5 + 15x - 1/20 = 1/3

2x/5 + 15x/1 - 1/20 = 1/3

MMC (5, 20, 3)

5, 20, 3 | 2

5, 10, 3 | 5

1, 2, 3 | 2

1, 1, 3 | 3

1, 1, 1 |_______

MMC = 2 . 5 . 2 . 3

MMC = 60

2x/5 + 15x/1 - 1/20 = 1/3

24x + 900x - 3 = 20

24x + 900x = 20 + 3

924x = 23

x = 23/924
