Respuesta:

:)

Explicación paso a paso:

a)

a/4 = 8

a = 8(4)

a = 32

b)

2y - 1 = 9

2y = 9 + 1

2y = 10

y = 10/2

y = 5

c)

2x - 1 = 8

2x = 8 + 1

2x = 9

x = 9/2

x = 4.5

d)

15 - 7 = 5c + 3c

8 = 8c

c = 8/8

c = 1

e)

1/3d + 3.4 = -4/5d + 1/2

1/3d + 4/5d = 1/2 - 3.4

5/15d + 12/15d = 0.5 - 3.4

17/15d = -2.9

1.133d = -2.9

d = -2.9/1.1333

d = 2.56

f)

0.1 + 0.4x = 0.3 + 5.4 - 4x

0.1 + 0.4x = 5.7 - 4x

0.1 - 5.7 = -4x - 0.4x

-5.6 = -4.04x

x = -5.6/-4.04

x = 1.39
