-18x+30-8x-8=-18-24x

-26x+24x=-18-22

+2x=-40

2x=40

x=40/2

x=20

Sério que você perguntou isso? Usa a regra do chuveirinho:

6.(-3)+6.5+(-4).2x+(-4).2=(-3).6+(-3).8x

-18+30-8x-8=-18-24x

-8x+24x=-18+18-30+8

-16x=-22 .(-1)

16x=22

x=16/22:2

x=8/11

6 ( – 3x + 5 ) – 4 ( 2x + 2 ) = –3 ( 6 + 8x )

– 18x + 30 – 8x – 8 = – 18 – 24x

18 + 30 – 8 = – 24x + 18x + 8x

40 = 2x

x = 40/2

x = 20

Ola Luiz

6*(– 3x + 5 ) – 4 ( 2x + 2 ) = –3 ( 6 + 8x )

-18x + 30 - 8x - 8 = -18 - 24x

-18x - 8x + 24x = -18 - 30 + 8

-2x = -40

x = -40/-2 = 20
