TrudyAnne:

Wait let me try.

Sam:

It's simple, what you've been given is x - 1 < 0 OR x - 1 > 4 So when x - 1 < 0, what is x? Likewise when x - 1 > 4, what's x?

YoursTruly:

I don't know. D:

Sam:

Well when x - 1 < 0, you solve for x. x - 1 < 0 Add both sides by 1 x < 1 When x - 1 > 4 Add both sides by 1 x > 5 Now we have x<1 and x>5, what will be your answer?

YoursTruly:

x < 1 OR x > 5?

Sam:

Mhm

YoursTruly:

Thank you!
