1) x-2/5=0,24 2) (7/3 . x -0,6) : 3 . 2/5=1
x =6/25+2/5 (7/3 . x -3/5) :3 = 1: 2/5
x =6/25+10/25 (7/3 . x -3/5) :3 = 5/2
x =16/25 7/3 . x -3/5 =5/2 . 3
7/3 . x -3/5 =15/2
7/3 .x =15/2+3/5
7/3. x = 81/10
x = 81/10 : 7/3
x =243/70
2) \(\left(\frac{7}{3}.x-0,6\right):3\frac{2}{5}=1\Rightarrow\left(\frac{7}{3}x-\frac{3}{5}\right):\frac{17}{5}=1\Rightarrow\left(\frac{7}{3}x-\frac{3}{5}\right)=\frac{17}{5}\Rightarrow\frac{7}{3}x=\frac{17}{5}+\frac{3}{5}=4\Rightarrow4:\frac{7}{3}=4.\frac{3}{7}=\frac{12}{7}=1\frac{5}{7}\)
