Question

9 5/13-(7 6/13-y)=2 3/13

Answer 1

9*5/13-(7*6/13-y) = 2*3/13

9*5/13-7*6/13+y = 2*3/13

3/13 + y = 2*3/13

y = 3/13

Answer 2

$9 frac{5}{13} -(7 frac{6}{13} -y)=2 frac{3}{13} \ \ \ 9 frac{5}{13} -7 frac{6}{13} +y=2 frac{3}{13} \ \ \ y=2 frac{3}{13}+7 frac{6}{13}-9 frac{5}{13} \ \ \ y=9 frac{9}{13}-9 frac{5}{13} \ \ \ y= frac{4}{13}$
