Answer:
x= 9 y=2
Step-by-step explanation:
Add up the equations vertically to eliminate y.
-x=-9
change the signs:
x=9
substitute the given value of x into the equation 2x-4y=10
2(9)-4y=10
18-4y=10
4y=8
y=2
Answer: 18% of youth used the internet elsewhere.
Step-by-step explanation:
At first, this problem might seem confusing since there could be places other than home with different percentages, and it feels as if you don't know enough to solve the problem.
But in reality, it breaks down to home or any other place in the world! If you're not at home, you need to exist somewhere.
So, it's actually as simple as 100% (you cannot have a total greater than 100% in the real world) - 82% = 18%
So, 18% of youth used internet in a place other than home.
