To solve this equation, first combine the like terms on the left side of the equation:

2x + 4x + 1/5 - 3/3 = 4
6x + 1/5 - 1 = 4
6x + 1/5 - 5/5 = 4
6x - 4/5 = 4

Now, isolate the x term by adding 4/5 to both sides of the equation:

6x - 4/5 + 4/5 = 4 + 4/5
6x = 4 + 4/5
6x = 20/5 + 4/5
6x = 24/5

Now, divide by 6 to solve for x:

x = 24/30
x = 4/5 or 0.8

Therefore, the solution to the equation is x = 4/5 or 0.8.
