Question

por favor ayuda urgente!!!

Answer 1

3x / 4 + 2x + 3x / 20 = 5 / 4 + 1 / 5

15x / 20 + 40x / 20 + 3x / 20 = 25 / 20 + 4 / 20

58x / 20 = 29 / 20

2x = 1

x = 1 / 2

x - (5x - 1) / 3 - 4x = - 3 / 5

3x / 3 - 5x / 3 + 1 / 3 - 12x / 3 = - 3 / 5

3x / 3 - 5x / 3 - 12x / 3 = - 3 / 5 - 1 / 3

- 14x / 3 = - 9 / 15 - 5 / 15

- 14x / 3 = - 14 / 15

x = 1 / 5
