Question

Solve a x - 12 = 9.
A. x = 21/a
B. x = 21/a
C. x = 3/a
D. x = 3/a

Answer 1

are you positive this is correct

Answer 2

you can only choose one

Answer 3

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 4

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 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.
