☆☞ [ Verified answer ]☜☆

(a-1)/a = 5

or

a - (1/a) = 5

Very different problems. If it is the former, you can solve for ‘a’ as the other answer states. If it is the later, multiple all terms by ‘a’.

a^2 -1 = 5a

a^2 - 5a - 1 = 0

And at this point, use the quadratic formula to find the two possible values of ‘a’. From there, just plug those values into the other formula.

Still two things to consider:

the other formula may be ambiguous as well

sometimes things that pop out of quadratic may not work in the original equation, or be complex numbers
