It seems like you're providing an equation or a function involving \( y \) and \( x \). We can evaluate or manipulate the expression \( 11x - 3y \) given that \( y = 12 \).
To substitute \( y = 12 \) into the expression \( 11x - 3y \):
Substitute \( y \): \[ 11x - 3(12) \]
Calculate \( -3(12) \): \[ -3(12) = -36 \]
Now your expression becomes: \[ 11x - 36 \]
If you have any specific questions or further instructions regarding this expression or any related topic, feel free to ask!
