Решите уравнения: 1)2 2/11x-5/16=1 3/4 2)4 2/9x+3 5/14=6 11/21

1) $2 \frac{2}{11}x- \frac{5}{16}=1 \frac{3}{4}$
$\frac{24}{11}x-\frac{5}{16}=\frac{7}{4}$
$\frac{24}{11}x=\frac{7}{4}+\frac{5}{16}$
$x=\frac{11}{24}*\frac{7*4+5}{16}$
$x=\frac{363}{384}$
$x=\frac{121}{128}$

2) $4 \frac{2}{9} x+3 \frac{5}{14} =6 \frac{11}{21}$
$\frac{38}{9} x=\frac{137}{21}-\frac{47}{14}$
Домножим обе части на 7
$7*\frac{38}{9} x=7*(\frac{137}{21}-\frac{47}{14})$
$\frac{266}{9} x=\frac{137*2}{3*2}-\frac{47*3}{2*3}$
$x=\frac{1}{2}*\frac{3}{2}$
$x=\frac{3}{4}$
