b) 3y + 1 = 10

c) y/2 = -1

d) x/3 = -3

e) y/3 = 3/2

f) x/3 = 7

g) y/4 = 8

h) x/2 = 1/3

i) y/5 = 1/3

​

Answer 1

Resposta:

a) y = 0

b) y = 3

c) y = -2

d) x = - 9

e) y = 9/2

f) x = 21

g) y = 32

h) x = 2/3

i) y = 5/3

Explicação passo-a-passo:

a) y vezes qualquer coisa seria zero

b) 3y = 10 - 1

3y = 9

y = 9/3

y = 3

c)y/2 = -1

y = (-1) . 2

y= -2

d) x/3 = -3

x = (-3) . 3

x = -9

e) y/3 = 3/2

y = (3/2) . 3

y = 9/2

f) x/3 = 7

x = 7 . 3

x = 21

g) y/4 = 8

y = 8 . 4

y = 32

h) x/2 = 1/3

x = (1/3) . 2

x = 2/3

i) y/5 = 1/3

y = (1/3) . 5

y = 5/3
