Answer 3

To solve the equation, we need to isolate the variable "x" on one side of the equation. Here's the step-by-step solution:

1. Combine the "x" terms on the left side of the equation: 8x - x = 7x

2. Combine the constants on the right side of the equation: 9 + 12 = 21

So now the equation becomes: 7x = 21

3. To isolate "x," divide both sides of the equation by 7: 7x / 7 = 21 / 7 x = 3

The solution to the equation is x = 3.
