Answer 1

Olá!!!

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 = - 3 / 10
ou
x = 10 / - 3
x = - 3,33.....

e) - 5x = - 12
x = - 12 / - 5
x = 2,4

f) - 4x = 8
x = 8 / - 4
x = - 2

g) - 3x = 9
x = 9 / - 3
x = - 3

h) - 5x = 15
x = 15 / - 5
x = - 3

Espero ter ajudado...
