Problema Solution
the equation y= -1777x+27153 can be used to predict the number y of gun deaths in united states x years after 2000 that is x=0 corresponds to 2000, x=2 corresponds to 2002 and so on predict the number of gun deaths in 2002 and 2005 in what year will the number of gun deaths be 7606

in year 2005 and 2009 x = 5 and 9 respectively
substitute 5 and 9 into the eqn
27153 - 1777 * 5
27153 - 1777 * 9
27153 - 1777 * x = 7606
x = (27153-7606)/1777
x+2000 will give you the year
