Answer:

x = [tex]y^{2}[/tex] - 4y + 12

Step-by-step explanation:

y = 2 + [tex]\sqrt{x-8}[/tex]

Put the 2 on the other side

y - 2 = [tex]\sqrt{x-8}[/tex]

Square both sides

[tex](y-2)^{2}[/tex] = x - 8

Expand the brackets

[tex]y^{2}[/tex] - 4y + 4 = x-8

Move 8 to the other side

x = [tex]y^{2}[/tex] - 4y + 12
