Answer:
x = abc/ (a+b)
Step-by-step explanation:
x/a + x/b = c
Multiply by ab to get rid of the fractions
ab(x/a + x/b) = abc
bx + ax = abc
Factor out an x
x( b+a) = abc
Divide each side by (a+b)
x ( a+b)/ (a+b) = abc/ (a+b)
x = abc/ (a+b)

Alright, let's interpret it, first.
The question is asking us to first find two percent of 23,000, then right an equation.
Alright, first, let's find two percent of 23,000. To find that we must do 0.02*23,000
I got 460
So we know that Mastertown's population is increasing by 460 people per year. All we have to do now is plug that into the equation.
Population (y)= 460* amount of years (x)
So our final equation is y = 460x
