Question

Resolva no campo dos numeros reais as inequaçoes:
2(x-2) +3 mior que 5 (x+1)

Answer 1

2 (x - 2) + 3 > 5 (x +1)
2x - 4 + 3 > 5x + 5
- 5x + 2x > 5 + 1
- 3x * (-1) > 6 * (- 1)
3x < - 6
x < $\frac{-6}{3}$
x < -2

Answer 2

2(x - 2) + 3 > 5.(x + 1)
2x - 4 + 3 > 5x + 5
2x - 1 > 5x + 5
2x - 5x > 5 + 1
- 3x > 6 ( - 1)
3x < - 6
x < - 6/3
x < - 2

R.: {x ∈ R / x < - 2}
