We can solve it using this method:

−3<x<5 all *-1 = 3>-x>-5 =

-5<-x<3-7<y<9We can sum the inequalities :

-7-5<y-x<9+3 = -12<y-x<12shreerajp99 wrote:

In the solution provided,the max value of y is taken as 9 whereas the min value of x is taken as -3.Is this a mistake in the question or we can ignore < and consider it as <= ?

To answer your question, you can ignore the "<" and consider it "<=": it makes no difference.
