Answer: x=12
This solution is not extraneous
Step-by-step explanation:
[tex]\frac{-4\sqrt{x-3}}{-4}=\frac{-12}{-4}[/tex] Divide both sides by -4
[tex]\sqrt{x-3}=3[/tex] Simplify
[tex]\left(\sqrt{x-3}\right)^2=3^2[/tex] Square both sides
[tex]3^2=9[/tex]
[tex]x-3=9[/tex]
add 3 on both sides
[tex]9+3=12[/tex]
[tex]x=12[/tex]
