Answer 1

Resposta:

olá...

Explicação passo-a-passo:

a)8x+2=2(x-3)

8x+2=2x-6

8x-2x=-6-2

6x=-8

x=-8/6

b)9x-2=5(x-3)

9x-2=5x-15

9x-5x=-15+2

-4x=-13

x=-13/-4

c)8x=16

x=16/8

x=2

d)-x=12

-x=12>>>.(-1)

x=12

e)-2x+13x=6

-2x+13x=6

11x=6

x=6/11

f)9x-4=10x-6

9x-10x=-6+4

-1x=2

x=2/-1

x=-1
