Twice the difference of a number and 10 is at most -22 . How do i write this?

Question

How do i translate this into an inequality

Answer 1

Twice the difference gives 2(difference). The difference of some number and ten is x-10. We always use the first number said first, so it wouldn't be 10-x.

So far we have 2(x-10). This is at most -22. "At most" is the same thing as saying less than or equal to.

So 2(x-10)≤-22.
