Question

If 2x + 5 = 17, what is x?

• A. 6
• B. 5
• C. 4
• D. 3

Hint:

Check your answer by plugging it back into the original equation: \(2(6) + 5 = 12 + 5 = 17\). The equality holds, so the answer is correct.

Answer 1

The Correct Option is A

Step 1: Understanding the Concept:
This is a two-step linear equation. The goal is to solve for the unknown variable \(x\).
Step 2: Detailed Explanation:
The given equation is:
\[ 2x + 5 = 17 \] First, subtract 5 from both sides of the equation to isolate the term with the variable:
\[ 2x = 17 - 5 \] \[ 2x = 12 \] Next, divide both sides by 2 to find the value of \(x\):
\[ x = \frac{12}{2} \] \[ x = 6 \] Step 3: Final Answer:
The value of \(x\) is 6. This corresponds to option (A).
