Answer:
Let's assume the number be 100.
According to the problem , 100 is increased by 100%.
So, new number will be 100+100=200
Now 200 will decreased by 20%.
So, 20% of 200= 0.20*200= 40.
So, again the number has been changed into 200+40=240.
So, x=240

Step-by-step explanation:
The equation for Zimbabwe's growth would be:
4x+1=12.6
Solve for x.
4x+1=12.6
Subtract 1 from both sides.
(4x+1)-1=(12.6)-1
4x=11.6
Divide both sides by 4.
(4x)/4=(11.6)/4
x=2.9
The approximate population of Zimbabwe in 1950 was 2.9 million.
