The equation y = 1777x + 27,153 can be used to predict the number y of gun deaths in the U.S.x years after 2000, that is x = 0 corresponds to 200, x2 corresponds to 2002,x5 crresponda with 2005, and so on. Predice the number of gun deaths in 2005 ad 2007. In what year will the number od deaths be 11,160?

So your equation is really
y = 1777 (year 2000) + 27153
so for 2007 for example
y = 1777 (20072000) + 27153
y = 12439 + 27153
= 39,592 in 2007
do other years the same way
for the second part unless you have a typo we are talking about before 2000
11,160 = 1777(year 2000 ) + 27153
1777(year2000) =  15993
year  2000 = 9
year = 1991
