To solve the equation 9x + 12 = 3x - 6:
First, we can simplify both sides of the equation:
9x + 12 - 12 = 3x - 6 - 12
This simplifies to:
9x = 3x - 18
Next, we can move the 3x term to the left side of the equation by subtracting 3x from both sides:
9x - 3x = 3x - 3x - 18
This simplifies to:
6x = -18
To isolate the variable x, we can divide both sides of the equation by 6:
6x/6 = -18/6
This simplifies to:
x = -3
Therefore, the solution to the equation 9x + 12 = 3x - 6 is x = -3.
9x + 12 = 3x -6
