Question

Resolve a inequação 1 - 2 > 1 - x+1/2

Answer 1

Explicação passo-a-passo:

$1 - 2 > 1 - x + \frac{1}{2} \\ 1 - 2 - 1 - \frac{1}{2} > - x \\ \frac{2 - 4 - 2 - 1 }{2} > - x\\ \frac{ - 2 - 2 - 1}{2} > - x \\ \frac{ - 4 - 1}{2} > - x \\ - \frac{5}{2} > - x \: \: \: \times ( - 1) \\ \frac{5}{2} > x$

Answer 2

1 - 2 > 1 - (x+1)/2

-1 > 1 - (x+1)/2

-1 -1 > (x+1)/2

-2 > (x+1)/2

-2 × 2 > x+1

-4 > x+1

-5 > x

ou

x < -5
