go the the ' matrix ' button , give the matrix a name , enter , dimension will be 3 x 4 , enter
1st row is 1..2...-1..-3...the number of the 1st equation..do same for the other 2
go to ' ops ' under the matrix menu , choose ' rref ' , enter the name , solve by ' enter '
4th column will be the answers if a triple exists...none of the ones offered
ahhh...you don't need anything to do with a matrix...c solves #1 , etc
the question is " which triple solves which equation !!!! "
