Answer 1

Explicação passo-a-passo:

a)4x-8>16

4x-8>16

4x>16+8

4x>24

x>24/4

x>6

b)-3x>-15

-3x>-15.(-1)

6x-24<4x-8

6x-4x<-8+24

2x<16

x<16/2

x<8

d)-4 (x-2)>12- 5x

-4.(x-2)>12-5x

-4x+8>12-5x

-4x+5x>12-8

x>4

e)3(×+5)>12x

3.(x+5)>12x

3x+15>12x

3x-12x >-15

-9x>-15.(-1)

9x<15

x<15/9

x<15÷3/9÷3

f)4(x-6)>2(x-4)-6

4.(x-6)>2.(x-4)-6

4x-24>2x-8-6

4x-24>2x-14

4x-2>-14+24

4x-2>10

4x>10+2

4x>12
