Lilith
[tex]x- \frac{1}{5}= 4x+\frac{2}{35} \\\\x-4x = \frac{2}{35}+ \frac{1}{5}\\\\-3x = \frac{2}{35}+ \frac{7}{35}\\\\-3x = \frac{9}{35}\ \ /*(-\frac{1}{3})\\\\x=-\frac{3}{35}[/tex]
x - 1/5 = 4x + 2/35
-x            -x           
    -1/5 = 3x + 2/35
  -2/35          -2/35
   -2/5 = 3x
      3       3
 -1/15 = x
