81/19 + x + 39/38 = 25/2
162/38 + x + 39/38 - 475/38 = 0
-274/38 + x = 0
x = 274/38
x = 7 8/38
x = 7 4/19

спасибо вам огромное

Answer 3

$4frac{5}{19} +x+1 frac{1}{38} =12 frac{1}{2} \ \ 4 frac{10}{38} +1 frac{1}{38}+x=12 frac{19}{38} \ \ 5frac{11}{38}+x= 12 frac{19}{38} \ \ x=12 frac{19}{38}-5frac{11}{38} x=7frac{8}{38}=7 frac{4}{19}$
