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...
