<u>Solution: </u>
From question given that
→ (1)
On substituting
in equation (1),

Taking 2 as a common in above expression,

Rewrite the above expression,
![=2\left[y^{2}+2(y)(9)+9^{2}\right]](https://tex.z-dn.net/?f=%3D2%5Cleft%5By%5E%7B2%7D%2B2%28y%29%289%29%2B9%5E%7B2%7D%5Cright%5D)

Hence Factor over complex numbers of
is 
Answer:
no solution.
Step-by-step explanation:
given that, y = 3x-1
so,
in equation, 3x-y = 9
putting the value of y here,
3x-(3x-1) = 9
3x-3x+1 = 9
3x and 3x is cancelled.
hence, no solution
