Question

5x + 3 + 1 sobre 2 maior ou igual a x sobre 3

Answer 1

$\frac{5x+4}{2} \geq \frac{x}{3} \\ \frac{3.(5x+4)}{6} \geq \frac{2x}{6} \\ 15x+12 \geq 2x \\ 13x \geq -12 \\ x \geq \frac{-12}{13}$

Answer 2

5 x + 3 + 1 /2 ≥ x/3
5 x + 4 /2 ≥ x/3
m.m.c = 6
3(5 x + 4 ) /6 ≥2 x/6 cortar o denominador
3(5 x + 4 ) ≥2 x
15 x + 12 ≥2 x
15 x - 2 x ≥ -12
13 x ≥ - 12
x ≥ -12/13
