Pfv rápido,vele bastante ponto

Answer 1

Salvew...

5(x - 1) > 6x - 8

5x - 5 > 6x - 8

5x - 6x > - 8 + 5

- x > - 3 . (- 1)

x < 3

x∈⟨- ∞ , 3]

Answer 2

Resposta:

$\sf 5 \cdot ( x - 1 ) > 6x - 8$

$\sf 5x - 5 > 6x -8$

$\sf 5x - 6x > -8 + 5$

$\sf - x > - 3 \quad \gets \text{ \sf Multiplicar por ( - 1), lembrando que inverte o sinal.}$

$\boldsymbol{ \sf \displaystyle x < 3 }$

$\boldsymbol{ \sf \displaystyle S = \{x\in\mathbb{R}\mid x < 3 \} }$
