Answer:
(x, y) = (-11, 4)
Step-by-step explanation:
You can subtract 3 times the second equation from the first to eliminate y.
(7x +9y) -3(x +3y) = (-41) -3(1)
4x = -44
x = -11
Substituting into the second equation gives ...
-11 +3y = 1
3y = 12
y = 4
The solution is (x, y) = (-11, 4).
The answer is 12 because you put -3 in the C places which gets you 9 – -3 and then you follow the signs which you would have to add them and get 12
Bilingual : trilingual = 14 : 3
So, ...
trilingual : total = 3 : (14+3) = 3 : 17
The number of trilingual denizens was (3/17)*3400 = 600.
