G)3.(x-1)-2x>13

por favor me ajudem ​

Answer 1

Olá, boa noite!

Resposta:

F) $\boxed{\color{red}{\mathsf{x < \dfrac{1}{2}}}}$

G) $\boxed{\color{red}{\mathsf{x>16}}}$

Explicação passo-a-passo:

F) 13x - 1 < 9x + 1

$\mathsf{13x-1<9x+1}$

$\mathsf{13x-9x<1+1}$

$\mathsf{4x<2}$

$\mathsf{x< \dfrac{2}{4} \longrightarrow \ x< \dfrac{1}{2}}$

______

G) 3 (x - 1) - 2x > 13

$\mathsf{3 (x - 1) - 2x > 13}$

$\mathsf{3x -3-2x>13}$

$\mathsf{3x-2x>13+3}$

$\mathsf{x > 16}$

Abraços!

Answer 2

F) 13x-1 < 9x+1

13x-9x < 1+1

4x < 2

x < 1/2

G) 3(x-1)-2x > 13

3x-3-2x > 13

x-3 > 13

x > 13+3

x > 16
