Answer 1

Ответ:

Пошаговое объяснение:

(2 7/9x+ 3 1/3)* 3/5= 1/6x+6 1/2

(25/9x + 10/3) * 3/5 = 1/6x +  13/2

5/3x + 2 = 1/6x + 13/2

5/3x - 1/6x = 13/2 - 2

10/6x - 1/6x = 9/2

9/6x = 9/2

x = 9/2 * 6/9

x = 3

Answer 2

$frac{3}{5}(2frac{7}{9}x + 3frac{1}{3}) = frac{1}{6}x + 6frac{1}{2}\\frac{3}{5}(frac{25}{9}}x + frac{10}{3}) = frac{1}{6}x + frac{13}{2}\\frac{3*25}{5*9}x + frac{3*10}{5*3} = frac{1}{6}x + frac{13}{2}\\frac{5}{3}x + 2 = frac{1}{6}x + frac{13}{2}\\frac{5}{3}x - frac{1}{6}x = frac{13}{2} - 2\\frac{10}{6}x - frac{1}{6}x = 6,5 - 2\\frac{9}{6}x = 4,5\\1,5x = 4,5\x = 3$
