Answer:
B) (5,-2)
Step-by-step explanation:
we have the equations:
We multiply the first equation by 3:
i will call this equation 1.
and we multiply the second equation by 2:
i will call this equation 2.
Now we subtract equation 2 from equation 1:
this is:
which gives:
and now that we know that 
we substitute this value in any of the original equations to find 
using 
we have:
so 
the answer is 
which is option B.
Volume of a cube: V = s^3, where s is the length of the edge.
So, the sum of them will be 1^3 + 2^3 = 9
