Gold courses have 18 holes.
each hole has a par, with either 3,4,5
the sum over the holes of one gold course is 78.
the number of par 5 holes is 6 more than the number of par 3 holes
if there are x holes with par 3, y holes with par 4 and z holes with par 5
write down a system of three linear equations linking these quantities
first two are easy
( 1 1 1 18 )
( 3 4 5 78 )
the third one I'm confused how to get to
( 1 0 1 7 ) ?
i solved using row echelon reduction and it dosen't work
the answers say -1 0 1 6
how does it get that?
how am i supposed to know that during a test?
please help
