Question 1169513
the original fraction is (x-2) / x
increase the numerator and denominator by 1 and you get (x-1) / (x+1)


you get (x-1) / (x+1) = 4/5
cross multiply to get 5*(x-1) = 4*(x+1)
simplify to get 5x-5 = 4x+4
subtract 4x from both sides of the equation and add 5 to both sides of the equation to get 5x-4x = 4+5
simplify to get x = 9


that's your answer.
the original fraction is 7/9.
add 1 to the numerator and denominator to get 8/10.
that simplifies to 4/5.


your solution is that the original fraction is 7/9.
