Question
The problem presented is as follows:

"If \( x = 5 \) and \( y = 7 \), what is the value of \( 2x - y \)?"

To solve this, substitute \( x = 5 \) and \( y = 7 \) into the expression \( 2x - y \):

\[ 2x - y = 2(5) - 7 \]

\[ = 10 - 7 \]

\[ = 3 \]

Thus, the value of the expression \( 2x - y \) is 3.
