Solution

n - 1

Solution steps

\frac{n - 7}{2} + \frac{n + 5}{2}

Join

\frac{n - 7}{2} + \frac{n + 5}{2} : \frac{2 n - 2}{2}

= \frac{2 n - 2}{2}

simplify (2+sqrt(8))/2 simplify

\frac{2 + 8}{2}

24 \geq - 3 b

(3-2(x-2))/6-(1+3(2-x))/4 <=-(3x-1)/(12)

\frac{3 - 2 ( x - 2 )}{6} - \frac{1 + 3 ( 2 - x )}{4} \leq - \frac{3 x - 1}{12}

∣ 4 x - 2 ∣ = ∣ x - 1 ∣
