Hello, BobRoss!

This one is tricky and dangerous.

There are several approaches.

I'll show you mine . . .

Like you, I split it into two inequalities: .

Note the "and"; we wantto be true.both

We'd like to multiply through by , but we must becareful!very

What we get depends on whether is positive or negative.

Suppose is positive.

Multiply both inequalities by

We have: .

. . . and: .

To make both statements true, we use: .

Suppose is negative.

Multiply both inequalities by negative

We have: .

. . . and: .

To make both statements true, we use: .

Solution: .
