To solve the equation, we can start by distributing the 4 to the terms inside the parentheses:

x.8 = 4x + 4

Next, we can subtract 4x from both sides of the equation to isolate the variable term:

x.8 - 4x = 4

Now, we can subtract x from both sides to combine like terms:

-3.2x = 4

Finally, we can divide both sides of the equation by -3.2 to solve for x:

x = 4 / -3.2

Simplifying the right side of the equation:

x = -1.25

Therefore, the solution to the equation is x = -1.25.
