Answer:
2x=0
x=0
Step-by-step explanation:
11-3x=5(2-x)+1
We first distribute the 5 to 2 and -x:
11-3x=10-5x+1
Combine like terms (combine all variables and then combine all constants)
-3x+5x=10+1-11
2x=0
x=0
The population of the country in 1990 is 249.5 million
<u>Step-by-step explanation</u>:
- Let 'x' be the population in 1990.
- The population in 2015 is 321.9 million.
The increase in x by 29% = 321.910^6
(since x is 100% and increase of 29% will be 129%)
129% of x = 321.910^6
1.29x = 321.910^6
x = 321.910^6/1.29
x = 249.510^6
x = 249.5 million.
∴ The population of the country in 1990 is 249.5 million
