I already understand the problem, but am having trouble with the algebra for textbook Fund of Physics Solutions, Halliday, 8e, Ch6 Prob 34. Copied here

I've been staring at this solution to N2L for hours and can't figure out how to go from the top 4 N2L equations to the bottom equation for f (friction). I tried making both 'as' and 'ab' as 'a' but keep geting back to the orig equation.
Just give me a hint, please...
