What is the value of the expression below when \( y=8 \) ? \[ 2 y-3 \]

To find the value of the expression \( 2y - 3 \) when \( y = 8 \), simply substitute 8 for \( y \): \[ 2(8) - 3 = 16 - 3 = 13. \] So, the value of the expression when \( y = 8 \) is 13. Now that we’ve nailed the math, let’s dive into a bit of educational fun! Did you know that algebra, as we know it, was developed by Persian mathematician Al-Khwarizmi in the 9th century? His influential work laid the groundwork for solving equations, like the one you just tackled! And if you’re looking to brush up on your math skills, try engaging with online platforms like Khan Academy or Art of Problem Solving. They offer interactive exercises that can make learning algebra feel more like a game and less like a chore!
