Question

502. Найдите корень уравнения:
х+4 1/8=-7 3/5​

Answer 1

Ответ:

$x+4\frac{1}{8} =-7\frac{3}{5}$

$x=-7\frac{24}{40} -4\frac{5}{40}$

$x=-11\frac{29}{40}$

$-x+(-31\frac{1}{3}) =40\frac{5}{12}$

$-x=40\frac{5}{12} +31\frac{4}{12}$

$x=-71\frac{3}{4}$

$-5\frac{3}{20} -x=3\frac{1}{8}$

$-x=3\frac{5}{40} +5\frac{6}{40}$

$x=-8\frac{11}{40}$

$-29\frac{3}{7} -x=-11\frac{4}{21}$

$-x=-11\frac{4}{21} +29\frac{9}{21}$

$x=-18\frac{5}{21}$
