These exercises refer to the following system: If we add 2 times the first equation to the second equation. The second equation becomes _______=____.
For the following exercise, create a system of linear equations to describe the behavior. Then, solve the system for all solutions using Cramer’s Rule. 64. Men aged 20 - 29, 30 - 39, and 40-49 made up 78% of the population at a prison last year. This year, the same age groups made up 82.08% of the population. The 20 - 29 age group increased by 20%, the 30 - 39 age group increased by 2%, and the 40 - 49 age group decreased to 34 of their previous population. Originally, the 30-39 age group had 2% more prisoners than the 20—29 age group. Determine the prison population percentage for each age group last year.
