Ethel was installing a sprinkler system. She cut a 20 m length of plastic tubing into two pieces. The longer piece was 2 m longer than twice the shorter piece.


Let l represent the length of the longer piece and let s represent the length of the shorter piece.


Choose the two equations that will create our system of equations for this story problem.



2s+2l=20


s=2l+2


l+s=20


l=2s+2
