Question

2. Решите уравнение плиз​

Answer 1

Ответ:

$(5\frac{1}{3}-3x):3=1\frac{4}{9}\\\\(\frac{16}{3}-3x ):3=\frac{13}{9}\\\\\frac{16}{3}-3x =\frac{13}{9}*3 \\\\\frac{48}{9}-3x =\frac{39}{9} \\\\-3x=\frac{39}{9}- \frac{48}{9}\\\\-3x=-\frac{9}{9}\\\\-3x=-1\\\\x=\frac{1}{3}$

Проверка:

$(5\frac{1}{3}-3*\frac{1}{3}):3=1\frac{4}{9} \\\\(\frac{16}{3}-\frac{3}{3}):3=\frac{13}{9}\\\\\frac{13}{3}:3=\frac{13}{9}\\\\\frac{13}{3}*\frac{1}{3}=\frac{13}{9}\\\\\frac{13}{9}=\frac{13}{9}$
