Помогите решить,пожалуйста [latex] \frac{3}{8}x=3 \frac{3}{8} [/latex] [latex] \frac{4}{7}x=-2 \frac{4}{7} [/latex] [latex] \frac{5}{6}x=4 \frac{4}{5} [/latex]

Ответ в приложении ^/$#@#$#@

[latex] \frac{3}{8}x = 3 \frac{3}{8} \\ \\ x= 3 \frac{3}{8} : \frac{3}{8} = \frac{27}{8} * \frac{8}{3} = \frac{9}{1} \\ \\ x=9 [/latex] проверим:  [latex] \frac{3}{8}* 9 = 3 \frac{3}{8} \\ \\ \frac{3*9}{8*1} =3 \frac{3}{8} \\ \\ \frac{27}{8} = 3 \frac{3}{8} \\ \\ 3 \frac{3}{8} =3 \frac{3}{8} \\ \\ [/latex] [latex]\frac{4}{7}x= -2 \frac{4}{7} \\ \\ x= -2 \frac{4}{7} :\frac{4}{7}= - \frac{18}{7} * \frac{7}{4} = - \frac{9}{2} \\ \\ x= -4 \frac{1}{2} \\ \\ \frac{4}{7}* (-4 \frac{1}{2} )= -2 \frac{4}{7} \\ \\ - \frac{4*9}{7*2} =-2 \frac{4}{7} \\ \\ - \frac{2*9}{7} = - 2 \frac{4}{7} \\ \\ - 2 \frac{4}{7} = - 2 \frac{4}{7} [/latex] [latex] \frac{5}{6}x=4 \frac{4}{5} \\ \\ x=4 \frac{4}{5}: \frac{5}{6} = \frac{24*6}{5*5} = \frac{144}{25} \\ \\ x= 5 \frac{19}{25} [/latex] проверим: [latex] \frac{5}{6} * 5 \frac{19}{25} =4 \frac{4}{5} \\ \\ \frac{5*144}{6*25} = 4 \frac{4}{5} \\ \\ \frac{1*24}{1*5} = 4 \frac{4}{5} \\ \\ 4 \frac{4}{5} = 4 \frac{4}{5} \\ \\ [/latex]
