Answer 1

Respuesta:

a) x + 1 = 6 x

1 = 6x - x

1 = 5x

1/5 = x

b) 3y = 21 y

21y - 3y = 0

18y = 0

y = 0/18 = 0

c) 2z + 1 = 21 z

1 = 21z - 2z

1 = 19z

1/19 = z

f) 7z - 1 = 34 z

- 1 = 34z - 7z

-1 = 27z

-1/27 = z

d) 4x – 3 = 29 x

-3 = 29x - 4x

-3 = 35x

-3/25 = x

e) 2y + 4 = 22 y

4 = 22y - 2y

4 = 20y

4/20 =y

1/5 = y

Answer 2

a). x + 1 = 6 x = x = 1/5

b). 3y = 21 y = y = 0

c). 2z + 1 = 21 z = z = 21/19

f). 7z - 1 = 34 z = z = - 1/27

d) 4x – 3 = 29 x = x = - 3/25

e). 2y + 4 = 22 y = y = 1/5
