responde pra mim ai pfv

Answer 1

1a)4x = 16,

x = 16/4

x = 4

----------------

1b)

2x-4 < 12,

2x > 12 + 4,

2x > 16,

x > 16/2,

x>8

----------------

1c) (cálculo muito grande, vou colocar o resumo)

x = 22/3

----------------

1d)4x - 4 = 12,

4x = 12 + 4,

4x = 16,

x = 16/4,

x = 4

-----------

1e)

6x + 6 = 15

6x = 15 -6

6x = 9

x = 9/6 : 3

x = 3/2
