Pam likes to practice dancing while preparing for a math tournament. She spends 80 minutes every day practicing dance and math.

To help her concentrate better on math, she spends 20 minutes more dancing than doing math.
Write a pair of linear equations to show the relationship between the number of minutes Pam practices math every day (x) and the number of minutes she practices dances every day (y).

I was always taught to use X (or the same letter) for both, it makes it a little easier to figure out. So X+(X+20)=80. ((X=Math, X+20=dance)) 2x+20=80, subtract 20 from both sides, 2x=60, divide both sides by 2, X=30. Now we substitute that in 30+(30+20)=80. So Pam practiced math 30 minutes and dance 50 :)
