Question

Решите уравнения [Помогите плиз]​

Answer 1

2) х=1/6+1/9
х=3/18+2/18
х=5/18

4) х=7/12-5/24
х=14/24-5/24
х=9/24
х=3/8

6)х=1/6+7/9
х=3/18+14/18
х=17/18

8)у=1/2-2/5
у=5/10-4/10
у=1/10

Answer 2

$x - \frac{1}{6} = \frac{1}{9 } \\ x - \frac{3}{18} = \frac{2}{18} \\ x = \frac{3}{18} + \frac{2}{18 } \\ x = \frac{5}{18}$

$x + \frac{5}{24} = \frac{7}{12 } \\ x + \frac{5}{24} = \frac{14}{24} \\ x = \frac{14}{24} - \frac{5}{24} \\ x = \frac{9}{24} = \frac{3}{8}$

$x - \frac{1}{6} = \frac{7}{9 } \\ x - \frac{3}{18} = \frac{14}{18} \\ x = \frac{14}{18} + \frac{3}{18} \\ x = \frac{17}{18}$

$y + \frac{2}{5} = \frac{1}{2} \\ y + \frac{4}{10} = \frac{5}{10} \\ y = \frac{5}{10} - \frac{4}{10} \\ y = \frac{1}{10}$
