Multiply both sides of the first equation by 3.
Multiply both sides of the second equation by 2.
6x + 9y = 3
-6x - 4y = -2
Now add them.
5x = 1
x = 1/5
Now plug in 1/5 for x in the first original equation.
2x + 3y = 1
2 * 1/5 + 3y = 1
2/5 + 3y = 1
2 + 15y = 5
15y = 3
y = 1/5
The solution is x = 1/5; y = 1/5.
There is one solution.

Step-by-step explanation:
5,004,300 would be your number in standard form.
Answer:
300
Step-by-step explanation:
The total number of ratio units in 6:5 is 6+5=11, so each of those ratio units must stand for 550/11 = 50 detectives. Then the 6 ratio units of police detectives stand for 6·50 = 300 police detectives.
