Question

el valor de x en las ecuaciones a)2/5-3x=4x-7/10 b) 4/3x+1/6=5/3x-1/2
​

Answer 1

A). = x = 11/70 ó x = 0,15

- 3x - 4x = - 7/10 - 2/5

- 7x = - 11/10

x = 11/70

x = 0,15

B). = x = 1/2 ó x = 0,5

4/3x + 1/6 = 5/3x - 1/2, x ≠ 0

4/3x - 5/3x = - 1/2 - 1/6

- 1/3x = - 2/3

1/3x = 2/3

3 = 6x

6x = 3

x = 1/2, x ≠ 0

x = 1/2

x = 0,5
