Height/ velocity
3m/12m per sec
Time= 0.25metres per seconds
To the nearest tenth, 0.3m per seconds
The would be something about 1779556
(hope this helps)
The answer is that y is equal to zero
Looks like the system is

We can eliminate
by taking




so that
, and



Substitute
into this last equation and solve for
:




Then



Plug these values into any one of the original equation to solve for
:




Hence the solution is x = 4, y = -3, and z = 2.
