Rozwiąż równanie ! Potrzebuję na jutro :) Dam Naj :) [latex]1 frac{2}{3} - 5c = 1 frac{1}{4} [/latex]

1 2/3 - 5c = 1 1/4 1 8/12 - 1 3/12 = 5c 5/12 = 5c /*12 5 = 60c /:60 5/60 = c

[latex]1 frac{2}{3} - 5c = 1 frac{1}{4} \\-5c=1frac{1}{4}-1frac{2}{3}\\-5c=1frac{3}{12}-1frac{8}{12}\\-5c=-frac{5}{12}/:(-5)\\c=-frac{5}{12}*(-frac{1}{5})\\c=frac{5}{60}[/latex]
