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 \( y \) When \( x=4 \) and \( y=2,3 x+5 y=22 \)

Let's solve it step by step. When \( x = 4 \) and \( y = 2 \), we substitute these values into the expression \( 3x + 5y \). Starting with \( 3x \): \( 3 \times 4 = 12 \) Now for \( 5y \): \( 5 \times 2 = 10 \) Adding those results together: \( 12 + 10 = 22 \) So, when evaluating \( 3x + 5y \) with the given values, you are correct that it equals 22! Now, remember that double-checking your calculations can save you from minor errors, like mistaking \( y \) as 3 instead of 2. Always good to keep those numbers straight!
