First few parts are just expansion, tedious but simple.
The last part i did was to compare to powers.
Since x^4 times x^3 divided by x^7 will give you x^0, their coefficients will give you the coefficient of x^0.

I’m sorry if this is obvious but how did the (1/x)^7 … line come about
I factorised out 1/x from both brackets. This makes it simpler when expanding the equation.
Thank you very much
