Answer 2

To solve the proportion, we need to find the missing values in the expression:

8,7 / 0,5 = x / (15 + 4x)

To solve for 'x', we can cross-multiply:

(8,7) * (15 + 4x) = (0,5) * x

Now, perform the calculations:

130.5 + 34x = 0.5x

Next, isolate the 'x' term on one side of the equation. Subtract 0.5x from both sides:

130.5 + 34x - 0.5x = 0

Combine 'x' terms:

33.5x = -130.5

Now, isolate 'x' by dividing both sides by 33.5:

x = -130.5 / 33.5

Calculate the value of 'x':

x ≈ -3.88

So, the missing value in the proportion is approximately -3.88.
