Question

resolva as inequação do 1°grau
5) 4x + 3 > 8 - X

6) 5.(x - 3) ≤ 4.(x+1)

7) 3(x+2) > 18​

Answer 1

Explicação passo-a-passo:

5) 4x + 3 > 8 - X

4x+x>8-3

5x>5

x>5/5

x>1

6) 5.(x - 3) ≤ 4.(x+1)

5x-15≤4x+4

5x-4x≤4+15

x≤19

7) 3(x+2) > 18

3x+6>18

3x>18-6

3x>12

x>12/3

x>4

Answer 2

Explicação passo-a-passo:

5) 5x > 5

x > 1

6)

5x - 15 ≤ 4x + 4
