Which best describes the solution of the followig system of inequalities? 3x+y<-13x+y<−1
y<-3x+3y<−3x+3

The solutions are the same as the solutions of y<-3x+3y<−3x+3

The solution region lies between the parallel boundary lines.

The solutions are the same as the solutions of 3x+y<-13x+y<−1

The solution region lies outside the parallel boundary lines.

Ithink the versus years?

The answer would be 5< 6n

So the first thing we do is to multiply the top equation by 3. the reason i want to do this is i notice there will be a 6y on both equations and can possibly add/subtract them. so we get 6y = -3x + 27. adding that and the second equation we get 6x = 27-15 which is 12. divide by 6 and we get 2. ∴ x = 2. substituting 2 into the first equation we get 2y = -2 + 9 which is 7. divide by 2 and we get 7/2. ∴ y = 7/2, x = 2.
