Question

If 2x - 3 = 9, what is the value of x?

• A. 3
• B. 4
• C. 5
• D. 6

Hint:

Quickly check your answer: plug \(x=6\) back into the original equation. \(2(6) - 3 = 12 - 3 = 9\). The equation holds, so the answer is correct.

Answer 1

The Correct Option is D

Step 1: Understanding the Concept:
This is a two-step linear algebraic equation. We need to isolate \(x\).
Step 2: Detailed Explanation:
The given equation is:
\[ 2x - 3 = 9 \] Add 3 to both sides of the equation:
\[ 2x = 9 + 3 \] \[ 2x = 12 \] Divide both sides by 2:
\[ x = \frac{12}{2} \] \[ x = 6 \] Step 3: Final Answer:
The value of \(x\) is 6. This corresponds to option (D).
