помогите решить уранение 3|2x-5|+1=5

Answer 1

$3 |2x - 5| + 1 = 5 \\ 3 |2x - 5| = 5 - 1 \\ 3 |2x - 5| = 4 \\ |2x - 5| = \frac{4}{3} \\ \\ 2x - 5 = \frac{4}{3} \\ 2x = \frac{4}{3} + 5 \\ 2x = \frac{19}{3} \\ x = \frac{19}{6} = 3 \frac{1}{6} \\ \\ 2x - 5 = - \frac{4}{3} \\ 2x = - \frac{4}{3} + 5 \\ 2x = \frac{11}{3} \\ x = \frac{11}{6} = 1 \frac{5}{6}$
Ответ: 1 5/6; 3 1/6.
