Answer:

x/3 + 3/x = 15/x

»x²/3x + 9/3x= 15/x

»x²+9/3x = 15/x

»x²+9 = 15/x × 3x

»x²+9= 45

»x²= 45-9

»x²= 36

»x=√36

»x= 6 which is not equal to 0

x/3+3/x = 15/x

((x × x) + (3×3)) / 3x = 15/x

( x^2 + 9) / 3x = 15 / x

3x × 15 = x ( x^2 +9)

45 x = x ^3 + 9x

45x - 9x = x^3

36x = x^3

36x/x = x^2

36 = x^2

x = √ 36

x = 6

Hope this will help...
