Answer 1

Ответ:

5 1/3х-1=1 1/9

5 1/3х=1 1/9+1

5 1/3х=2 1/9

х=2 1/9:5 1/3

х=19/48

Answer 2

$\displaystyle5\frac{1}{3}x-1=1\frac{1}{9} \\\\\displaystyle5\frac{1}{3}x=1\frac{1}{9}+1 \\\\\displaystyle5\frac{1}{3}x=2\frac{1}{9} \\\\\displaystyle x=2\frac{1}{9}:5\frac{1}{3} \\\\\displaystyle x=\frac{19}{9}:\frac{16}{3} \\\\\displaystyle x=\frac{19}{\not{9}_3}*\frac{\not{3}}{16} \\\\\displaystyle x=\frac{19}{3*16} \\\\\displaystyle x=\frac{19}{48}$
