Question
solve each inequality algebraically and give the answer by using interval notation.
5-9y <_ (less than or equal to) 19-2y
I got -2y <_ (less than or equal to) y; (-2, infinity]. But the back of the book answer says [infinity, -2). What am I doing wrong?

Does it really make a difference in which order the solutions are given? You have the same solutions.
