Answer 1

2(x-3)+3(x-1)<36

2x - 6 + 3x - 3 < 36

5x - 9 < 36

5x < 36 + 9

5x < 45

x < 45/5

x < 9

Answer 2

Resposta:

$S=\{x\,\in\,\mathbb{R}\,|\,x<9\}$

Explicação passo-a-passo:

$2(x - 3) + 3(x - 1) < 36 \\ 2x - 6 + 3x - 3 < 36 \\ 2x + 3x < 36 + 6 + 3 \\ 5x < 45 \\ x < \frac{45}{5} \\ x < 9$
