Answer:

Step-by-step explanation:

13 years

Step-by-step explanation:

Let the number of years be x

Village x:

Initial population = 68000

Decrease in 1 year = 1200

Decrease in x year = 1200x

Village y:

Initial population = 42000

Increase in 1 year = 800

Increase in x year = 800x

Solve x:

When both villages have the same population

68000 - 1200x = 42000 + 800x

2000x = 26,000

x = 26000 ÷ 2000 = 13

Answer: The two villages will have equal number of population in 13 years.
