Answer 1

Resposta:

Explicação passo a passo:

A) -X = 9

(-X = 9) * -1

X = -9

B) -X = 2

(-X = 2) * -1

X = 2

C) -7X = 14

X = 14/-7

X = -2

D) -3X = 10

X = 10/-3

E) -5X = -12

X = -12/-5

F) -4X = 8

X = 8/-4

X = -2

G) -3X = -9

X = -9/-3

X = 3

H) -5X = 15

X = 15/-5

X = -3

I) -2X = -10

X = -10/-2

X = 5

J) 15 = -3X

X = 15/-3

X = -5

K) -40 = -5X

X = -40/-5
