To solve the equation ax - 12 = 9, you would first add 12 to both sides of the equation to isolate the variable term:

ax - 12 + 12 = 9 + 12
ax = 21

Then, you would divide both sides of the equation by "a" to solve for x:

ax/a = 21/a
x = 21/a

Therefore, the solution to the equation ax - 12 = 9 is x = 21/a.

The correct answer is D. x = 21/a.

Answer 2

To solve the equation ax - 12 = 9, we can follow these steps:

Step 1: Add 12 to both sides of the equation:
ax - 12 + 12 = 9 + 12
ax = 21

Step 2: Divide both sides of the equation by a:
ax/a = 21/a
x = 21/a

Therefore, the solution to the equation ax - 12 = 9 is x = 21/a, which corresponds to option D.
