# C1 Inequality Help watch

1. Im unsure on how to do the number line part... ugh. Could anyone help. thanks
2. You've done 10-2x<5 wrong, when you divide by a negative number you have to switch the inequality sign.

Yep. Why didn't you just move the 2x across as well as the 5?

You'd get 5<2x and just divide by 2. No need to mess around with negatives.

Yes.

When you draw the number line, you just need to see the region where it overlaps, to see where both inequalities hold.
