Question

What is the value of x in the equation 2x + 5 = 13?

• A. 3
• B. 4
• C. 5
• D. 6

Hint:

Solve linear equations by isolating the variable step-by-step and verify by substitution.

Answer 1

The Correct Option is B

To find the value of \(x\) in the equation \(2x + 5 = 13\), follow these steps:

1. Start with the equation: \(2x + 5 = 13\).
2. Subtract 5 from both sides to isolate the term with \(x\):

\[2x + 5 - 5 = 13 - 5\]

\[2x = 8\]

3. Divide both sides by 2 to solve for \(x\):

\[\frac{2x}{2} = \frac{8}{2}\]

\[x = 4\]

Therefore, the value of \(x\) is 4.
