Answer:

x ≤ -21

Explanation:

x + 18 ≤ - 3

Our objective here is to get x by itself using inverse operations

It's important to note that the inverses for basic algebra are

  • Addition and Subtraction
  • Multiplication and Division

Using this knowledge we can easily solve

x + 18 ≤ - 3

Here, 18 is being added to x. We want to get rid of this. The inverse of addition is subtraction so we must subtract 18 but whatever we do to one side we must do to the other, so we subtract 18 from both sides

x + 18 - 18 ≤ - 3 - 18

==> simplify

x ≤ -21

X is by itself so we are done.
