Question

5/18x + 2 целых 1/2= 10 целых 5/6... Решить уравнение

Answer 1

5/18*x=10 5/6-2 1/2
5/18*x=10 5/6-2 3/6
5/18*x=8 2/6
x=8 1/3:5/18
x=25/3*18/5
x=30

Answer 2

$\frac{5}{18}x + 2 \frac{1}{2} = 10 \frac{5}{6}$
$\frac{5}{18}x = 10 \frac{5}{6} -2 \frac{1}{2}$
$\frac{5}{18}x = 10 \frac{5}{6} -2 \frac{3}{6}$
$\frac{5}{18}x = 8 \frac{2}{6}$
$\frac{5}{18}x = \frac{25}{3}$
$x = \frac{25}{3} : \frac{5}{18}$
$x = \frac{25}{3} * \frac{18}{5}$
$x=5*6$
$x=30$
