b) x - 5 = 15
c) x - 3 = 2
d) x + 4 = 8
e) x + 3 = 1
f ) 2x = - 8
g) 3y = 18
h) 2x = 0
i ) 2x + 4 = 6
j ) 3y + 1 = 10​

Answer 1

Resposta:

a) x = 12

b) x = 20

c) x = 5

d) x = 4

e) x = - 2

f ) x = - 4

g) y = 6

h) x = 0

i ) x = 1

j ) y = 3

Explicação passo-a-passo:

a) x - 2 = 10

x = 10 + 2

x = 12

b) x - 5 = 15

x = 15 + 5

x = 20

c) x - 3 = 2

x = 2 + 3

x = 5

d) x + 4 = 8

x= 8 -4

x = 4

e) x + 3 = 1

x= 1 - 3

x = - 2

f ) 2x = - 8

x = - 8/2

x = - 4

g) 3y = 18

y = 18/3

y = 6

h) 2x = 0

x = 0/2

x = 0

i ) 2x + 4 = 6

2x = 6 - 4

2x = 2

x = 2/2

x = 1

j ) 3y + 1 = 10​

3y = 10 - 1

3y = 9

y = 9/3

y = 3
