Answer 1

Respuesta:

a) x= 2

b) x= -2

c)x= -8

d)x= +3

Answer 2

Explicación paso a paso:

a) 4(x + 3) + 5 = 25

4x + 12 + 5 = 25

4x + 17 = 25

4x = 25 - 17

4x = 8

x = 8:4

x = 2

b) - 5 (x + 2) + 16 = 26

-5x - 10 + 16 = 26

- 5x + 6 = 26

-5x = 26 - 6

-5x = 20

x = 20 : (-5)

x = - 4

c) 14 + 3(x + 4) = 2

14 + 3x + 12 = 2

3x + 26 = 2

3x = 2 - 26

x = - 24 : 3

x = - 8

d) 28 - (x + 5) = 20

28 - x - 5 = 20

- x + 23 = 20

- x = 20 - 23

- x = - 3

x = 3

Espero te ayude!!!!
