The popultion of Medford High is 800 students & the population of WEstville High is 1240 students. Medfords pop. has been increasing by 30 students per year, while westville has been decreasing by 25 students per year. In how many yearas will the populations be the same. how many students will that be?
I got 8 yrs 1040 students, but doing it long way.
Pls show me how to solve alg way
800 + 30x = 1240 -25x
55x = 440
x = 8 (years from now)
