Answer:
y₁=x₁+0.04x₂
y₂=x₂+0.06x₁
Step-by-step explanation:
In the first year, number of people who live:
In the city= x₁
In the suburb=x₂
New Population in the next year
In the city= y₁
In the suburb=y₂
If each year 6% of the city population moves to the suburb,
New Suburb Population=Previous Population+Immigrants
y₂=x₂+0.06x₁
If each year 4% of the suburb population moves to the city,
New City Population=Previous Population+Immigrants
y₁=x₁+0.04x₂
y₁=x₁+0.04x₂
y₂=x₂+0.06x₁
Multiply them back into each other... You would multiply your answer with the number you divided by (the number ouside the table if you used the table... ) and you should get the larger number you divided.
Basically you know that the 2 wholes from both sides cancel out.
Set up the equation, 5/8 = 3/12 + 3/x
3/x = 5/8 - 3/12
Set them to have a common denominator, 3/x = 15/24 - 6/24
3/x = 9/24
Simplify 9/24 and you will get 3/8
3/x = 3/8
Obviously this means x = 8
