[tex]\displaystyle 1)-\frac{1}{5}(-\frac{5}{9}x-\frac{10}{9})=-\frac{1}{5}(-\frac{5}{9}x)-\frac{1}{5}(-\frac{10}{9})=\frac{1}{9}x+\frac{2}{9}\\ \\2)0,2(10-0,5x)=0,2*10-0,2*0,5x=2-0,1x[/tex]

Verified answer

Пошаговое объяснение:

-1/5(-5/9х - 10/9) = 5/45х + 10/45 = 1/9х + 2/9

0,2(10 - 0,5х) = 2 - 0,1х
