You can put this solution on YOUR website! During four football games,a California high school team scored 22 times. They either scored 7 points with a touchdown and the point after or 3 points with a field goal. The team scored a total of 134 points. How many field goals did the team make?
-----
Equations:
Scores Eq.:::: s + t = 22 scores
Points Eq.::::7s + 3t= 134 points
-------
Multiply thru "Scores" by 7:
7s + 7t = 7*22
7s + 3t = 134
-------------------
Subtract and solve for # of field goals:
4t = 20
t = 5 (# of 3-point field goals)
