F) x -12 -6x = -18 + 6
G) 18 - 8x + 6x = 5x + 32

Answer 1

Respuesta:

hola!!

A) 5x + 28 =-32

5x = -32 - 28

5x = -60

x = -60 / 5

x = -12

B) 9x + 8 =71

9x = 71 - 8

9x = 63

x = 63 / 9

x = 7

C) 32 = 6x - 7 × (-2)

32 = 6x + 14

32 - 14 = 6x

18 = 6x

18 / 6 = x

3 = x

D) x + 7x + 12 = -13 × 4

8x + 12 = -52

8x = -52 - 12

8x = -64

x = -64 / 8

x = -8

E) -8 × 6 - 3 × 14 = 12x + 6x

-48 - 42 = 18x

-90 = 18x

-90 / 18 = x

-5 = x

F) x -12 -6x = -18 + 6

-5x -12 = -12

-5x = -12 + 12

-5x = 0

x = 0 / -5

x = 0

G) 18 - 8x + 6x = 5x + 32

18 -2x = 5x + 32

-2x - 5x = 32 - 18

-7x = 14

x = 14 /-7

x = -2
