Answer 2

Let's begin by simplifying the left side of the equation:

1,2 - (-0,125*(x-4)) = 2,1

1,2 + 0,125*(x-4) = 2,1 (remember that subtracting a negative is the same as adding a positive)

Next, let's isolate the variable on one side of the equation. We can start by subtracting 1,2 from both sides:

0,125*(x-4) = 2,1 - 1,2

0,125*(x-4) = 0,9

Now, we can divide both sides by 0,125 to solve for x:

(x-4) = 0,9 / 0,125

(x-4) = 7,2

x = 7,2 + 4

x = 11,2

Therefore, the solution to the equation is x = 11,2.
