in a rocket launching, the height h meter, the rocket reaches after t sec for the moment it was launched is given by h=xtyt
the rocket altitude after 2 sec is 40 metres, and after 3 sec is 45 metres.
a. find x and y
b. altitude rocket after 5 sec

40 = 2 x  2 y
45 = 3 x  3 y
120 = 6 x  6 y
090 = 6 x  6 y
inconsistent, no solution
