Answer:
country a = 19,812 cars
country b = 6,604 cars
Step-by-step explanation:
a = country a
b = country b
the 2 eqations are:
a + b = 26,416
a = 3b
now substitute 3b for a in the first equation:
3b + b = 26,416
add the variables:
4b = 26,416
now divide 26,416 by 4 (26,416/4)
b = 6,604
so country b has 6,604 cars
to find country b, substitute the number of cars in country b (which is 6,604) in the second equation:
a = 3 × 6,604
a = 19,812
so country a has 19,812 cars
