Question

resolver las ecuaciones y hacer la verificación de cada una.​

Answer 1

Explicación paso a paso:

c) 32 = 6x - 7 . (-2)

32 = 6x + 14

-6x = 14 - 32

-6x = -18

x = 3

32 = 6(3) - 7(-2)

32 = 18 + 14

32 = 32

d) x + 7x + 12 = -13 . 4

8x + 12 = -52

8x = -52 - 12

8x = -64

x = -8

-8 + 7(-8) + 12 = -13 . 4

-8 - 56 + 12 = -52

-64 + 12 = -52

-52 = -52

e) -8 . 6 - 3 . 14 = 12x + 6x

-48 -42 = 18x

-90 = 18x

18x = -90

x = -5

-8 . 6 - 3 . 14 = 12(-5) + 6(-5)

-48 - 42 = -60 - 30

-90 = -90
