Question

6× - 3 (4 - 2×) < 5× - 8

Answer 1

Olá...

6× - 3 (4 - 2×) < 5× - 8

6x - 12 + 6x < 5x - 8

12x - 12 < 5x - 8

12x - 5x < - 8 + 12

7x < 4

x < 4/7

x ∈ |R / x < 4/7

Bons estudos.

Answer 2

Resposta:

6x - 3(4 - 2x) < 5x - 8

6x - 12 + 6x < 5x - 8

12x - 12 < 5x - 8

12x - 5x < - 8 + 12

7x < 4

x < 4/7

S = {x ∈ IR / x < 4/7}
