Answer 1

( 1 )

$\displaystyle\\x-5\frac{1}{4}=6\frac{1}{4}\\\\\\x= 6\frac{1}{4}+5\frac{1}{4}\\\\\\x=11\frac{2}{4}\\\\\\x=11\frac{1}{2}$

Проверка:

$\displaystyle\\11\frac{1}{2}-5\frac{1}{4}=6\frac{1}{4}\\\\\\11\frac{2}{4}-5\frac{1}{4}=6\frac{1}{4}\\\\\\6\frac{1}{4}=6\frac{1}{4}$

( 2 )

$\displaystyle\\x+5\frac{1}{9}=7\frac{4}{9}\\\\\\x=7\frac{4}{9}-5\frac{1}{9}\\\\\\x=2\frac{3}{9}\\\\\\x=2\frac{1}{3}$

Проверка:

$\displaystyle\\2\frac{1}{3}+5\frac{1}{9}=7\frac{4}{9}\\\\\\2\frac{3}{9}+5\frac{1}{9}=7\frac{4}{9}\\\\\\7\frac{4}{9}=7\frac{4}{9}$
