0.2*(x-1)+0.5(3x-9)=x/3-2

Question

0.2*(x-1)+0.5(3x-9)=x/3-2

Answer 1

0,2x-0,2+1,5x-4,5=1/3*x-2
1,7x-1/3*x=-2+4,7
1 21/30*x-10/30*x=2 7/10
1 11/30*x=2 7/10
x=2 7/10:1 11/30
x=27/10*30/41
x=81/41
x=1 40/41

Answer 2

0.2*(x-1)+0.5(3x-9)=x/3-2
0,2x-0,2+1,5x-4,5=x/3-2|*3
0,6x-0,6+4,5x-13,5=x-6
5,1x-x=-6+0,6+13,5
4,1x=8,1|:41
x=81/41=1 40/41
