Answer:
4x + 6
Step-by-step explanation:
Given
+ 
Before we can add the fractions we require them to have a common denominator.
Factor the denominator of the first fraction
+ 
Multiply the numerator / denominator of the second fraction by (x + 2)
=
+
← fractions now have a common denominator
Add the numerators leaving the denominators
= 
= 
=
← simplified sum with numerator 4x + 6
There shouldn't be a negative in front of one of the equations.
5x-4=16. I hope this helps :)
184 - 124 = 60
so it has grown by 60 in 18 months. That is 3 1/3 per month.
so Number of citizens depending on month is 124 + (1 1/3)n
or 124 + 4n/3:
At population 1000:-
124 + 4n/3 = 1000
4n/3 = 1000-124
n = (1000-124) * 3/4 = 657 months
