Answer:
[tex]x=\pm \sqrt{6-2y}[/tex]
[tex]$y=\frac{1}{2} (6-x^2)$[/tex]
Step-by-step explanation:
[tex]x^2+(y-1)\cdot 2 =4[/tex]
[tex]x^2+2y-2 =4[/tex]
[tex]x^2+2y =6[/tex]
I will solve it for [tex]x[/tex]
[tex]x^2 =6-2y[/tex]
[tex]x=\pm \sqrt{6-2y}[/tex]
Solving for [tex]y[/tex]
[tex]$y=3-\frac{x^2}{2} $[/tex]
[tex]$y=\frac{1}{2} (6-x^2)$[/tex]
