Answer:
what is the question
Step-by-step explanation:
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.
The ratio is 14:5, as 42 divided by 3 is 14 and 15 divided by 3 is 5.
