Changing the position and resize the Graphic Logo Image in Template

Can anyone help me as soon as possible?

I am trying to insert a new custom graphic logo inside of a wordpress theme but cannot adjust the logo to shift up and then to the left so it is neatly spaced between the header navigation and the slider images just below. Here is where the logo is:

The original graphic logo size was:

174×50

I need the new graphic logo to be;

640×209

Can anyone help? I can’t see where to adjust or change this is the style.css

Here’s the current upper part of the style.css:
