Question

resultado 5-3.(×+6),<×-14

Answer 1

5 - 3( x + 6 ) < x - 14

5 - 3x - 18 < x - 14

- 3x - x < - 14 - 5 + 18

- 4x < - 1 *(-1)

4x > 1

x > 1 / 4

ou

x > 0,25

Answer 2

5-3.(x+6) < x-14

5-3x-18 < x-14

-3x-13 < x-14

-3x-x < -14+13

-4x < -1  *(-1)

4x > 1

 x > 1/4

Resposta → S= {x ∈ R | x > 1/4}
