Question

Express , twelve times a number minus six is less than or equal to

negative eighteen as an equation

Answer 1

12x - 6 ≤ - 18

Explanation:

We will call "a number" x so

Twelve times a number would be:

12x

Then minus 6

12x - 6

Now we add the less than or equal to sign.

12x - 6 ≤

This is equal to negative eighteen, so:

12x - 6 ≤ - 18

As a bonus we can also solve for x.

12x - 6 = - 18 Add 6 to each side.

12x - 6 + 6 = -18 + 6

12x = -18 + 6

12x = -12 Divide each side by 12

12x/12 = -12/12

x = -12/12

x = -1

So we can say when x ≤ -1 Then 12x - 6 ≤ -18
