Пошаговое объяснение:

[tex]3 \frac{1}{3} x + 2 \frac{1}{2} = 2 \frac{2}{3} x + 3 \frac{1}{3} [/tex]

[tex] \frac{10}{3} x + \frac{5}{2} = \frac{8}{3} x + \frac{10}{3} [/tex]

[tex]20x + 15 = 16x + 20[/tex]

[tex]20x - 16x = 20 - 15[/tex]

[tex]4x = 5[/tex]

[tex]x = \frac{5}{4} [/tex]

[tex]x = 1 \frac{1}{4} [/tex]

[tex]x = 1.25[/tex]

Ответ:

3 1/3 * x + 2 1/2 = 2 2/3 * x + 3 1/3

10/3 * x + 5/2 = 8/3 * x + 10/3

20x + 15 = 16x + 20

20x - 16x = 20 - 15

4x = 5

x = 5/4 или х = 1,25
