Решите уравнение 2)-(5 2/3-1,6)-x=6 1/3 4)x-(-4,6+3 4/7)=-8 1/14

2) $-(5 \frac{2}{3}-1,6)-x=6$
$-5 \frac{2}{3}+1 \frac{6}{10}-x=6$
$-5 \frac{2}{3}+1 \frac{3}{5}-x=6$
$-5 \frac{10}{15}+1 \frac{9}{15}-x=6$
$-4 \frac{1}{15}-x=6$
$x=6+(-4 \frac{1}{15})$
$x=5 \frac{15}{15}-4 \frac{1}{15}$
$x=1 \frac{14}{15}$
4) $x-(-4.6+3 \frac{4}{7})=-8 \frac{1}{14}$
$x+4.6-3 \frac{4}{7}=-8 \frac{1}{14}$
$x+4.6=-8 \frac{1}{14}+3 \frac{4}{7}$
$x+4.6=-7 \frac{15}{14}+3 \frac{8}{14}$
$x+4.6=-4 \frac{7}{14}$
$x+4.6=-4 \frac{1}{2}$
$x+4.6=-4 \frac{5}{10}$
x+4.6=-4.5
x=-4.5-4.6
x=-9.1
