(X - 1) / X = 5 /6 (We use the cross multiplication): 6 (X - 1) = 5 X; 6X - 5X = 6; X = 6

You could simply use the cross-multiply method, multiply the numerator of the first fraction to the denominator of the second fraction and vice versa:
6(x-1)=5x
Then simplify to solve for x:
6x-6=5x
6x-5x=6
x=6 :D
