Question

(x-5$\frac{1}{12}$)+7$\frac{5}{18}$=9
$\frac{4}{9}$

Answer 1

Ответ:

x = 29/4, x = 7 1/4

$(x - 5 \frac{1}{12} ) + 7 \frac{5}{18} = 9 \frac{4}{9} \\ (x - \frac{61}{12} ) + \frac{131}{18} = \frac{85}{9} \\ x - \frac{61}{12} + \frac{131}{18} = \frac{85}{9} \\ x + \frac{79}{36} = \frac{85}{9} \\x = \frac{85}{9} - \frac{79}{36} \\ x = \frac{29}{4} . \: x = 7 \frac{1}{4}$
