Question

7 5/24-x=2 5/16, (x+5/12)-9/20=11/15
​

Answer 1

1)173/24-х=37/16

-х=37/16-173/24

-х=-235/48

х=4 43/48

2)(x+5/12)-9/20=11/15

х+5/12-9/20=11/15

х-1/30=11/15

х=11/15+1/30

х=23/30

Answer 2

Во втором ответ: х = 23/30$1)   7 \frac{5}{24}-x=2 \frac{5}{16}\\\\-x = 2 \frac{5}{16} - 7 \frac{5}{24}\\\\-x = 2 \frac{15}{48} - 7 \frac{10}{48}\\\\-x = 2 \frac{15}{48} - 7 \frac{10}{48}\\\\\\-x = 2 \frac{15}{48} - 6 \frac{58}{48}\\ \\\\-x = -4 \frac{43}{48}\\\\\\x = 4 \frac{43}{48}\\\\\\\\\\\\2) (x+\frac{5}{12})-\frac{9}{20}=\frac{11}{15}\\\\x+\frac{5}{12}-\frac{9}{20}=\frac{11}{15}\\\\x=\frac{11}{15} + \frac{9}{20} - \frac{5}{12}\\\\x=\frac{44}{60} + \frac{27}{60} - \frac{25}{60}\\\\x=\frac{46}{60}$
