First, let's distribute and simplify both sides of the equation:

8 0.7x - 8 4 = 2 0.2x - 2 3 - 39
5.6x - 32 = 0.4x - 6 - 39

Now, combine like terms:

5.6x - 32 = 0.4x - 45

Next, get all the x terms on one side of the equation:

5.6x - 0.4x = -45 + 32

Simplify:

5.2x = -13

Finally, solve for x:

x = -13 / 5.2
x = -2.5

Therefore, the solution to the equation is x = -2.5.
