There are two numbers that multiply to -45 and combine to 12. Find
the two numbers, then the LARGER
number is your answer for this question.

The large number is 15

Step-by-step explanation:

15 * (-3) = -45

15 + (-3) = 12

  x = 1

Step-by-step explanation:

If your "system of equations" is supposed to be ...

  f(x) = g(x)

the two function values are equal in January, for x = 1. The number of imports is equal to the number of exports in that month. Both f(x) and g(x) are 3 for x=1.

___

There are no "equations" involved here. There are only tables for f(x) and g(x). We assumed the relevant equation was f(x)=g(x), but that is not given as part of the problem statement.

If your "system of equations" is ...

then the solution is (x, y) = (1, 3) as described above.
