Пожалуйста решите уравнение : 1) x+3/20=5/12+2/9 2) 5/7-y=1/54+1/9+10/27 3) (4/5-k)-1/3=1/6-1/10

[latex]x+\cfrac{3}{20}=\cfrac{5}{12}+\cfrac{2}{9}\\x+\cfrac{3}{20}=\cfrac{23}{36}\\x=\cfrac{22}{45}[/latex] [latex]\cfrac{5}{7}-y=\cfrac{1}{54}+\cfrac{1}{9}+\cfrac{10}{27}\\\cfrac{5}{7}-y=\cfrac{1}{2}\\y=\cfrac{3}{14}[/latex] [latex]\left(\cfrac{4}{5}-k\right) - \cfrac{1}{3}=\cfrac{1}{6}-\cfrac{1}{10}\\\cfrac{4}{5}-k=\cfrac{2}{5}\\k=\cfrac{2}{5}[/latex]
