Hi there!
To complete these table operations you have to plug in the value from the left part of the table into the equation on the left part of the table. I'll do the first one for you to help you visualize this.
v = 4, w = 2, and the equation is 3v + w.
We plug in the "v" value into the equation 3v + w to get 3 * 4 + w. Since we know what "w" is we can plug that in as well to get 3 * 4 + 2 and from that we can solve.
3v + w <--- Equation.
3 * 4 + w <--- Plug in the v value.
3 * 4 + 2 <--- Plug in the w value.
12 + 2 <--- 3 * 4 = 12
14 <--- Final answer.
Hope this helps! Contact me if you still don't understand. :)
