Question

Решите уравнения а) 4 8/13-x=1 5/13 б) x+1 3/14=3 9/14 в) 2 11/15+x=5 2/15 г) x-2 5/16=4 13/16 д)5 15/19-x=3 3/19 e) x+1 11/18=3 7/18 заранее

Answer 1

$4 \frac{8}{13}-x=1 \frac{5}{13}; \\ x= 4 \frac{8}{13}-1 \frac{5}{13}; \\ x= 3 \frac{3}{13} .$

$x+ \frac{13}{14}=3 \frac{9}{14}; \\ x= 3 \frac{9}{14}- \frac{13}{14}; \\ x=2 \frac{10}{14}; \\ x=2 \frac{5}{7};$

$2 \frac{11}{15}+x=5 \frac{2}{15} ; \\ x=5 \frac{2}{15}-2 \frac{11}{15}; \\ x=2 \frac{6}{15}; \\ x=2 \frac{2}{5} .$

$x-2 \frac{5}{16}=4 \frac{13}{16}; \\ x=2 \frac{5}{16}=+4 \frac{13}{16}; \\ x=6 \frac{18}{16}; \\ x=7 \frac{2}{16}; x=7 \frac{1}{8} .$

$5\frac{15}{19}-x= 3 \frac{3}{19} ; \\ x= 5\frac{15}{19}-3 \frac{3}{19}; \\ x=2 \frac{12}{19} .$

$x+1 \frac{11}{18}=3 \frac{7}{18} ; \\ x= 3 \frac{7}{18}-1 \frac{11}{18}; \\ x=1 \frac{14}{18} ; x=1 \frac{7}{9}$
