Question

(\frac{x - 10}{9} = -4)（with some handwritten steps like (-32 = x - 10) etc.）

Explanation:

Step1: Let denominator = $a$, cross-multiply

$$x - 10 = -4 \times a$$

Step2: Substitute $a=8$ (from handwritten note)

$$x - 10 = -4 \times 8$$
$$x - 10 = -32$$

Step3: Isolate $x$, add 10 to both sides

$$x = -32 + 10$$

Answer:

$x = -22$
