Question

ayudaaa mañanaaa tengo que tenerlo hecho​

Answer 1

Respuesta:

Explicación paso a paso:

a) 2 - x = 6x - 12

2 + 12 = 6x + x

14 = 7x

14/7 = x

2 = x

b) x - 3 + 5x = 7 - 9x

6x - 3 = 7 - 9x

6x + 9x = 7 + 3

15x = 10

x = 10/15

x = 2/3 = 0,66666

c) x - 2x = 4x - 6x

-x = -2x

-x + 2x = 0

x = 0

d) -( 1 - x) = 10 * (-2 + x)

-1 + x = -20 + 10x

-1 + 20 = 10x - x

19 = 9x

19/9 = x

2,111 = x

e) 4 * (3x - 2) - x = (5x + 1) * 2

12x - 8 - x = 10x + 2

11x - 8 = 10x + 2

11x - 10x = 2 + 8

x = 10
