Question

Rezolvați inecuatia x/2-1<1/6 Va rog multor!

Answer 1

Răspuns:

Explicație pas cu pas:

$\dfrac{x}{2}-1<\dfrac{1}{6}\\\dfrac{x}{2}<\dfrac{1}{6}+1\\\dfrac{x}{2}<\dfrac{7}{6}\\x<2\cdot \dfrac{7}{6}\\x<\dfrac{7}{3}\\x\in\left(-\infty,\dfrac{7}{3}\right)$

Answer 2

Răspuns:

    x < $\frac{7}{3}$

Explicație pas cu pas:

    $\frac{x}{2}-1<\frac{1}{6}$

    $\frac{x}{2}<\frac{1}{6}+\frac{1}{1}$

    $\frac{x}{2}<\frac{1}{6}+\frac{6}{6}$

    $\frac{x}{2}<\frac{7}{6}$

    6x < 14

    x < 14 ÷ 6

    x < $\frac{14}{6}$

    x < $\frac{7}{3}$
