Question

1. Resolvemos las siguientes ecuciones:

a) - 6 ( z - 1 ) = - 5 ( z + 2 )

b) 4 ( 2× - 4 ) = - 2 ( × + 3 )

c) 2 - ( × + 5 ) = 4× - 8

d) 8× + 2 ( × - 4 ) = 8× + 12

e) 6 - ( n + 3 ) - 3n + 5 - 2n​

Answer 1

Respuesta:

a) Z=16

Explicación paso a paso:

-6z+6=-5z-10

-6z-5z=-10-6

-z=-16

z=16

Answer 2

a)

-6z + 6 = -5z - 10

-6z + 6 = -5z = - 10 - 6

-z = - 10 - 6

-z = - 16

z = 16

b)

8x - 16 = - 2x - 6

4x - 8 = - x - 3

4x + x = - 3 + 8

5x = - 3 + 8

5x = 5

x = 5/5

x = 1

c)

2 - x - 5 = 4x - 8

- 3 - x = 4x = - 8 + 3

- x - 4x = - 8 + 3

- 5x = - 8 + 3

- 5x = - 5

x = - 5/ - 5

x = 1

d)

4x + x - 4 = 4x + 6

5x - 4 = 4x + 6

5x - 4x = 6 + 4

x = 6 + 4

x = 10

e)

6 - n - 3 - 3n + 5 - 2n

6 - n - 3 - 3n + 5 - 2n

8 - 6n
