Step 1:
Let's solve this systematically:

Step 2:
: Rearrange the second equation to express y in terms of x

From $$x^{2} - y = 6$$, we can derive:
y = x^{2} - 6

Step 3:
: Substitute this expression into the first equation

x^{2} + (x^{2} - 6)^{2} = 6
Substituting y = x^{2} - 6:

Step 4:
: Expand the substituted equation

x^{2} + x^{4} - 12x^{2} + 36 = 6

Step 5:
: Rearrange to standard form

x^{4} - 11x^{2} + 30 = 0

Step 6:
: This is a quadratic in x^{2}.

Let $$u = x^{2}
u^{2} - 11u + 30 = 0

Step 7:
: Solve the quadratic

(u - 5)(u - 6) = 0
u = 5$$ or $$u = 6

Step 8:
: Find corresponding x values

If $$u = x^{2} = 5$$, then $$x = \pm\sqrt{5}
If u = x^{2} = 6, then x = \pm\sqrt{6}

Step 9:
: Check solutions

For each x value, calculate corresponding y using $$y = x^{2} - 6

Final Answer

Infinitely many solutions The key insight is that the system has multiple solution pairs that satisfy both equations, making it an infinite solution system.
