Between 2000 and 2010, coal and petroleum production from the fuel- producing countries can be modeled by the following system of equations,
where x = 0 represents the year 2005:
Coal production: y = 93.2x + 3100
Petroleum production: y=-29.1x + 2942
Calculate the
year in which production from both forms of fuel was equal.
