Question

resuelve las siguientes ecuaciones​

Answer 1

Respuesta:

Explicación paso a paso:

a) x - 5 (2x - 3) = 3 (x - 1) + 4

x - 10x - 15 = 3x - 3 + 4

-9x - 15 = 3x + 1

-9x - 3x = 1 + 15

-12x = 16

x = 16/-12

Simplificamos:

x = 4/-3

b) 2(x - 5)/3 + 4 = 5x - 2

2x - 10 + 12 = 5x - 2

2x + 2 = 5x - 2

2x - 5x = -2 - 2

-3x = -4

x = 4/3

c) 3 - (x + 2)/5 = 5 ( 3x - 2)

15 - x + 2 = 15x - 10

75x - x + 2 = 15x - 10

75x - 15x = -10 + 2

60x = -8

x = -8/60

d) 3 ( x - 4) + 10 = 13 - x

3x - 12 +´10 = 13 - x

3x - 2 = 13 - x

3x + x = 13 + 2

4x = 15

x = 15/4
