Write the solution in compact form:?

Question

Write the solution in compact form:

h + 1 < 2/3 h < h + 2

And then how is that written in interval notation?

Answer 1

Subtract h from all intervals:

1 &lt; -h/3 &lt; 2

Multiply through by -3:

-3 &gt; h &gt; -6

In interval notation:

(-6, -3)

Edit:  Whoops.  Had the endpoints in the wrong order.
