To solve for x, we want to get all the x's on one side of the equation.

First, let's get rid of the fractions. We can do this by multiplying both sides of the equation by 5:

5(2x - 5) = 5(3/5)x + 5(4)
10x - 25 = 3x + 20

Next, let's get all the x's on one side by subtracting 3x from both sides:

10x - 3x - 25 = 3x - 3x + 20
7x - 25 = 20

Now, add 25 to both sides to solve for x:

7x - 25 + 25 = 20 + 25
7x = 45

Finally, divide by 7 to get the final value of x:

x = 45 / 7 = 6.43
