Answer 2

To solve this proportion, we'll use the cross-multiplication method. The proportion is:

$\frac{x - 9}{-1} = \frac{-2}{-0.5}$

First, let's solve for the right-hand side of the proportion:

$\frac{-2}{-0.5} = 4$

Now, the proportion becomes:

$\frac{x - 9}{-1} = 4$

Next, cross-multiply to solve for $x$:

$-1 \times 4 = x - 9$

$-4 = x - 9$

Add 9 to both sides to isolate $x$:

$x = -4 + 9$

$x = 5$

So, the value of $x$ that satisfies the proportion is $5$.
