(x-3целых9/13)+5целых10/13=12целых4/13 помогите

Answer 1

$(x-3\frac{9}{13})+5\frac{10}{13} =12\frac{4}{13} \\\\(x-3\frac{9}{13})=12\frac{4}{13}-5\frac{10}{13}\\\\x-3\frac{9}{13}=11\frac{17}{13}-5\frac{10}{13}\\\\x-3\frac{9}{13}=6\frac{7}{13}\\\\x=6\frac{7}{13}+3\frac{9}{13}\\\\x=9\frac{16}{13} = 10\frac{3}{13}$
