Hi guys,

I've been having some trouble solving the below equation for B:

I have a blind spot for this one and I need to get on the right path. What is the first step to solving this?

hi William F

I'd start by multiplying both sides by the denominator:

hi bobbym,

Nice to hear from you. Hope you are well.

It took you longer to write the whole thing whereas I just did line 1.

Thanks to both of you! I was able to solve with bobs push in the right direction and I was able to check my work with bobbyms contribution.

hi bobbym

I'm very well thanks. We had a wonderful week at Lake Bled in Slovenia. Now got a pile of jobs to catch up on. Today, clear out the 'work room' so the electrician can put in new ceiling lights. Better go and start moving files.

Hi;

Did you get to see that structure on the island in the middle of the lake?

I have the result, but I do not yet know how to get it.

It's the Pilgrimage Church of the Assumption of Mary. You can row out to it but we didn't. It is a popular place for weddings. There are 90 steps up from the lakeside and tradition requires that the groom carry his bride up all 90. Our guide was naturally asked what happens if he drops her. She just said the wedding is off!

Whew! 90 steps. It certainly says something about the grooms desire and the bride's dietary habits.

I have the result, but I do not yet know how to get it.

It's a mountainous region so I'm quessing they are pretty fit generally. Perhaps, these days the roles reverse after 45 steps.

True, today's gal can kick, punch and scream all the way up those stairs while carrying a full grown man. Saw that in a movie...

Here's a couple of pics. One from the hillside shwoing a view of the island; and one from the nearest point lakeside, showing the steps.
