Solve a x - 12 = 9.

Question

A. x = 21/a
B. x = 21/a
C. x = 3/a
D. x = 3/a

Answer 1

To solve the equation \( ax - 12 = 9 \), we first isolate \( ax \):

1. Add 12 to both sides: \[ ax = 9 + 12 \] \[ ax = 21 \]

2. Now, divide both sides by \( a \) to solve for \( x \): \[ x = \frac{21}{a} \]

So the solution is \( x = \frac{21}{a} \).

The correct answer matches with options A and B: A. x = 21/a
B. x = 21/a

Thus, both A and B are correct.

Answer 2

are you positive this is correct

Answer 3

Yes, I'm confident in the solution provided. Here’s a step-by-step breakdown again:

Given the equation: \[ ax - 12 = 9 \]

1. Add 12 to both sides: \[ ax = 9 + 12 \] \[ ax = 21 \]

2. Divide both sides by \( a \) (assuming \( a \neq 0 \)): \[ x = \frac{21}{a} \]

Thus, the solution is indeed: \[ x = \frac{21}{a} \]

The answer corresponds to both options A and B. If you have any further questions or need clarification, feel free to ask!

Answer 4

you can only choose one

Answer 5

Understood! Since both options A and B are identical and valid, you can choose only one.

I would suggest selecting A. \( x = \frac{21}{a} \) as your answer.
