Answer:

3

Step-by-step explanation:

the positive answer for this equation is

x=(3,-3)

so the positive answer is:3

Answer: [tex]x=3[/tex]

Subtract 1/3x² from both sides

[tex]0-\frac{1}{3} x^2=\frac{1}{3} x^2-3-\frac{1}{3} x^2[/tex]

[tex]-\frac{1}{3} x^2=-3[/tex]

Divide both sides by -1/3

[tex]-\frac{1}{3} x^2/\frac{1}{3} =-3/-\frac{1}{3}[/tex]

[tex]x^2=9[/tex]

Take square root

x=±√9

[tex]x=3[/tex]
