Answer:

Step-by-step explanation:

The given equation is 9 = 3 × (-12). To solve this two-step equation, we need to isolate the variable on one side of the equation. We can do this by first dividing both sides of the equation by 3:

9/3=3×(−12)​/3

This simplifies to:

3=−12

Step-by-step explanation:

The equation is 9 = 3x - 12.

First, let's add 12 to both sides of the equation to isolate the term with the variable on one side.

9 + 12 = 3x - 12 + 12
