Question: Solving For A Variable

I was using Maple to solve some basic algebraic equations for my chemistry course, and came across a quirky behavior that has me baffled. When I type: (-5.05)(23.83-100)c = (4.186)(10)(23.83-22) I can right click on that input and solve for the variable c. If instead, however, I type: (-5.05)(c)(23.83-100) = (4.186)(10)(23.83-22) then Maple only gives me the option to isolate the expression for "c(-76". Can someone explain to me why Maple is doing this so I can better understand what is happening "behind the scenes?" Also, if it helps, I'm using Maple 11. Thank you!
