B)x+4=6-8x
C)4y+10=4+6y
D18x-43=65
E)23x-16=14-17x
F)10y-5(1+y)=3(2y-2)-20
G)1/5y +24=y
H)1/6-x/2=-2x/3+1/4​

Answer 1

Resposta:

Explicação passo-a-passo:

a) 10x = 0-4 = 4

x = 4/10 = 2/5 (dividido por 2)

b) x+8x = 6-4

9x = 2

x = 2/9

c) 4y-6y = 10-4

2y = 6

y = 6/2 = 3

d) 18x = 65+43

18x = 108

x = 108/18 = 6

e) 23x+17x = 14+16

40x = 30

x = 30/40 = 15/20 (dividido por 2)

f) 10y-5y = 6y-6-20

5y-6y = -6-20

y = 26

g) 1/5y-y = 24

y/5-y/1 = 24

y/5-5y/5 = 24

y/5-5y/5 = 24

y-5y/5 = 24

-4y/5 = 24

5*24 = 120

y = 120/-4 = -30

h) 1/6-1/4 = -2x/3+x/2

4-6 = -3x+6

4-6+6 = -3x

4 = -3x

4/-3 = x
