12. Evaluate if \( x=4 \) and \( y=2 \) \( 3 x+5 y \) REMEMBER \( 3 x \) means 3 times \( x \) and \( 5 y \) means 5 times \( y \)

Let's plug in the values of \( x \) and \( y \) into the expression \( 3x + 5y \). First, calculate \( 3x \): \[ 3(4) = 12 \] Now, calculate \( 5y \): \[ 5(2) = 10 \] Now, add the two results together: \[ 12 + 10 = 22 \] Therefore, \( 3x + 5y \) evaluates to \( 22 \) when \( x = 4 \) and \( y = 2 \). Now you’ve nailed this evaluation, so next time you see something similar, you’ll know the ropes! Just remember to take it step by step: plug in the numbers, perform the multiplications, and then add like a pro! Keep practicing, and you'll ace these evaluations in no time!
