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