Answer 2

To solve the equation (-8.5:-2,5+(x-1)) = 20.4, we'll go through the steps:

1. Simplify the expression inside the parentheses: (-8.5 : -2.5 + (x - 1)) = 20.4

   The expression (-8.5 : -2.5) means dividing -8.5 by -2.5. Dividing -8.5 by -2.5 gives us a positive value:

   3.4 + (x - 1) = 20.4

2. Remove the parentheses by distributing the addition: 3.4 + x - 1 = 20.4

   Simplify further: x + 2.4 = 20.4

3. Subtract 2.4 from both sides of the equation: x + 2.4 - 2.4 = 20.4 - 2.4

   Simplify further: x = 18

So, the solution to the equation (-8.5:-2,5+(x-1)) = 20.4 is x = 18.
