Question

РЕШИТЕ УРАВНЕНИЯ!!!
Х - 1 5/7 = 2 1/7
(12 5/13 + У) - 9 9/13= 7 7/13

Answer 1

х=2 1/7 +1 5/7
х= 3 6/7

12 5/13 +у- 9 9/13=7 7/13
у=7 7/13+9 9/13 -12 5/13
у=4 11/13

Answer 2

$x-1 frac{5}{7} =2 frac{1}{7} \ x=2 frac{1}{7} +1 frac{5}{7} \ x=3 frac{6}{7} \ \ (12 frac{5}{13}+y)-9 frac{9}{13} =7 frac{7}{13} \ 12 frac{5}{13} +y=7 frac{7}{13} +9 frac{9}{13} \ 12 frac{5}{13} +y=16 frac{16}{13} \ y=16 frac{16}{13} -12 frac{5}{13} \ y=4 frac{11}{13}$
