Question

What is the solution set of -9x ≤ 27?

Answer 1

x is greater and equal to 3

Answer 2

To get rid of the x, you must do the opposite. So divide the -9 to the other side. The other side would be a 3. Now, when you divide a negative, the sign would flip. Instead of the sign being lesser than or equal to, it would change to greater than or equal to:

x ≥ 3
