x = a number
4 less than 5 times itself mean :
5 x - 4
x + 5 x - 4 = 27
6 x - 4 = 27 Add 4 to both sides
6 x - 4 + 4 = 27 + 4
6 x = 31 Divide both sides by 6
x = 31 / 6
Are you shure that the result is 27?

Bosnian, you are correct
if the number is 31/6
then
31/6 + 5(31/6) - 4
= 31/6 + 155/6 - 4
= 31-4
= 27
if the number is 31/6
then
31/6 + 5(31/6) - 4
= 31/6 + 155/6 - 4
= 31-4
= 27
