Answer 2

The correct answer is "9/20".

Step-by-step explanation:

$The \ given \ expression \ is :\\\\3x+\frac{1}{5} =2-x\\\\On \ adding \ "x" \ both \ sides,we \ get\\\\3x+\frac{1}{5}+x=2-x+x\\\\4x+\frac{1}{5}=2\\\\On \ subtracting \ "\frac{1}{5}" \ from \ both \ sides,we \ get\\\\4x+\frac{1}{5}-\frac{1}{5}=2-\frac{1}{5}\\\\4x=2-\frac{1}{5}\\\\On \ taking \ LCM,we \ get\\4x=\frac{10-1}{5}\\\\4x=\frac{9}{5}\\\\On \ applying \ cross \ multiplication,we \ get \\20x=9\\x=\frac{9}{20}$
