Решите уравнение:1)х+5/7=(-3/8)*1 1/3;2)у-7/12=3 1/2*(-4/7);Заранее спасибо

1. [latex]x+\frac{5}{7}=(-\frac{3}{8})*1\frac{1}{3}[/latex] [latex]x=(-\frac{3}{8})*\frac{3*1+1}{3}-\frac{5}{7}[/latex] [latex]x=-\frac{3*4}{8*3}-\frac{5}{7}[/latex] [latex]x=-\frac{12}{24}-\frac{5}{7}[/latex] [latex]x=-\frac{1}{2}-\frac{5}{7}[/latex] [latex]x=\frac{-7-10}{14}[/latex] [latex]x=-\frac{17}{14}[/latex] [latex]x=-1\frac{3}{14}[/latex] 2. [latex]y- \frac{7}{12} =3 \frac{1}{2} *(- \frac{4}{7} )[/latex] [latex]y=\frac{3*2+1}{2} *(- \frac{4}{7} )+\frac{7}{12}[/latex] [latex]y=-\frac{7*4}{2*7}+\frac{7}{12}[/latex] [latex]y=-2+\frac{7}{12}[/latex] [latex]y=\frac{-24+7}{12}[/latex] [latex]y=-\frac{17}{12}[/latex] [latex]y=-1\frac{5}{12}[/latex]
