It would appear you have two x values. I don't know what you mean by finding the x values.

I am guessing you need to find the area under the standard normal curve.

Just use the table and subtract the two values.

From the table:

z=0 corresponds to the mean and it's value is 0.5

z=-1.444... corresponds to 0.07436...

0.5-0.07436=0.425

Here's a graph of your region. I assume this is what you're meaning.
