Some election data can be modeled by the following system of equations --
x + 2y = 47
-x + 2y = 27
where x is the years after 1996, and y is the percentage of group A voters in the first equation, and y is the percentage of group B voters in the second equation. Use the addition method to determine in which year the percentage of voters from group A will be the same as the percentage of voters from group B. For that year, what percent will be from group A and what percent will be from group B ?
In which year will the percentage of voters from group A be the same as the percentage of voters from group B ?
What percentage will be from group A and what percent will be from group B that year ?
Provide complete and step by step solution for the question and show calculations and use formulas.
