Question

Resolva as Equacoes Abaixo:

A) 2x+20= 0
B) 3x+2x-10+13-28= 0
C) x+30 = 40
D) 20-80+2x= 10
E) 5x - 4= 6x+8
F) w-5= -2w + 22

Answer 1

Resposta:

A) 2x + 20 = 0

2x = -20

x= -20/2

x= -10

B) 3x+2x-10+13-28=0

3x+2x= 10+28-13

5x=25

x=25/5

x= 5

C)x+30=40

x=40-30

x=10

D)20-80+2x=10

2x=10+80-20

2x=70

x=70/2

x=35

E)5x-4=6x+8

5x-6x= 8+4

-x= 12

F)w-5=-2w+22

w+2w=22+5

3w=27

w=27/3

w=9
