A small country emits 125,000 kilotons of
carbon dioxide per year. In a recent global
agreement, the country agreed to cut its
carbon emissions by 2.2% per year for the
next 8 years. In the first year of the
agreement, the country will keep its
emissions at 125,000 kilotons and the
emissions will decrease 2.2% in each
successive year. How many total kilotons
of carbon dioxide would the country emit
over the course of the 8 year period, to the
nearest whole number?

Arrange the steps to solve this system of linear equations in the correct sequence. x + y = -2 2x – 3y = -9 tiles subtract 3x + 3y = -6 (obtained in step 1) from 2x – 3y = -9 (given) to solve for x. substitute the value of x in the first equation (x + y = -2) to get y = 1. the solution for the system of equations is (-3, 1). x = -15 the solution for the system of equations is (-15, 13). add 3x + 3y = -6 (obtained in step 1) to 2x – 3y = -9 (given), and solve for x. x = -3 substitute the value of x in the first equation (x + y = -2) to get y = 13. multiply the first equation by 3: 3(x + y) = 3(-2) 3x + 3y = -6.
