The Correct Option is B

Solution and Explanation

Step 1: Solve for \( y \).
From the equation \( y - x = 2 \), substitute \( x = 55 \): \[ y - 55 = 2 \Rightarrow y = 57. \]
Step 2: Solve for \( 2x + y \).
Now, calculate \( 2x + y \): \[ 2(55) + 57 = 110 + 57 = 167. \]
Step 3: Conclusion.
Thus, the value of \( 2x + y \) is 167.
