where x=amount of points scored in the first game
Add up all the x's and you get

Solve for x


The question asks the score for the second game and the score for the second game is 6 times as much as the first
Therefore, we know that in the equation

that 6x is the second equation
"Plug" in "x" for 6x where

Sue scored 30 points in the second game
