Question

Решите уравнение ( x + 3 2\9) : 4 1\6=6

Answer 1

$(x+3\frac{2}{9}):4\frac{1}{6}=6\\(x+\frac{29}{9}):\frac{25}6}=6\\(x+\frac{29}{9})*\frac{6}{25}=6\\\frac{6}{25}x+\frac{58}{75}=6\\18x+58=450\\18x=450-58\\18x=392\\x=\frac{196}{9}=21\frac{7}{9}$

Answer 2

$(x + 3 \frac{2}{9} ) \div 4 \frac{1}{6} = 6 \\ (x + \frac{29}{9} ) \div \frac{25}{6} = 6 \\ (x + \frac{29}{9}) \times \frac{6}{25} = 6 \\ \frac{6}{25} x + \frac{58}{75} = 6 \\ 18x + 58 = 450 \\ 18x = 450 - 58 \\ 18x = 392 \\ x = 21 \frac{7}{9}$
