Answer:

subtract 3

Explanation:

You want to "undo" what is done to x. It usually works well to do that in reverse order. Here, x is ...

  • multiplied by 2
  • had 3 added to the product

To undo these steps, you start by undoing the addition of 3.

__

1st step: subtract 3 from both sides.

2nd step: divide both sides by 2

_____

As with equations, whatever you do to one side of the inequality must also be done to the other side. When we say "subtract 3", we mean "subtract 3 from both sides of the inequality."
