Answer provided by our tutors
let
p = the population in 1950
the population of Zimbabwe was about 12 6 million, which was 1 million more than 4 times the population in 1950
126 = 1 + 4*p
1 + 4*p = 126
4*p = 126 - 1
4*p = 125
p = 125/4
p = 31.25 millions
in 1950 the population in Zimbabwe was 31.25 millions.
