Final answer:

To solve the equation 12 = 9r - 6x + 15, isolate the variable by manipulating the equation. Divide both sides of the equation by 9 to solve for r. The equation is equal to r - 6x - 3.

Step-by-step explanation:

To solve the equation, we need to isolate the variable. Start by adding 6x and 15 to both sides of the equation:

12 + 6x - 15 = 9r + 15 + 6x - 15

-3 + 6x = 9r

Next, divide both sides of the equation by 9 to solve for r:

(-3 + 6x) / 9 = (9r) / 9

-1/3 + 2/3x = r

Therefore, the equation 12 = 9r - 6x + 15 is equal to r - 6x - 3.
