Question

1. \\( 12 = -9 + \frac{x}{-3} \\)

Explanation:

Step1: Isolate the fraction term

Add 9 to both sides.
$12 + 9 = \frac{x}{-3}$

Step2: Simplify left-hand side

Calculate the sum of 12 and 9.
$21 = \frac{x}{-3}$

Step3: Solve for x

Multiply both sides by -3.
$x = 21 \times (-3)$

Step4: Compute final value

Calculate the product.
$x = -63$

Answer:

$x = -63$
