Need a little help with these problems:

1. (Solve equation for the given variable)

ax + by + c = 0 for x



2. (Express answer in simplest form in terms of the given variable)

The base and height of a triangle are consecutive odd integers, and the height exceeds the base. If the base is B cm, find the area of the triangle.

Can anyone tell me how to do these please??

Okie dokie lets see if i still got my talent =D
1. ax+by+c = 0

First, you have to get the x by itself, so you subtract the by and the c:

ax+by+c= 0
-by = 0

ax+c= 0+by
-c = 0-by

So now you have:
ax = 0 - by - c

See how the sign changed?

Now what you do is divide ax by a so all you have left is x, make sure you do it to both sides.

Oh, God. I was never good at this. Sorry, I cant get this one... =((
