y-2=6x-6-4\sqrt{2}x+4\sqrt{2}
Use the distributive property to multiply 6-4\sqrt{2} by x-1.
6x-6-4\sqrt{2}x+4\sqrt{2}=y-2
Swap sides so that all variable terms are on the left hand side.
6x-4\sqrt{2}x+4\sqrt{2}=y-2+6
Add 6 to both sides.
6x-4\sqrt{2}x+4\sqrt{2}=y+4
Add -2 and 6 to get 4.
6x-4\sqrt{2}x=y+4-4\sqrt{2}
Subtract 4\sqrt{2} from both sides.
\left(6-4\sqrt{2}\right)x=y+4-4\sqrt{2}
Combine all terms containing x.
\frac{\left(6-4\sqrt{2}\right)x}{6-4\sqrt{2}}=\frac{y+4-4\sqrt{2}}{6-4\sqrt{2}}
Divide both sides by 6-4\sqrt{2}.
x=\frac{y+4-4\sqrt{2}}{6-4\sqrt{2}}
Dividing by 6-4\sqrt{2} undoes the multiplication by 6-4\sqrt{2}.
x=\frac{\left(2\sqrt{2}+3\right)\left(y+4-4\sqrt{2}\right)}{2}
Divide y+4-4\sqrt{2} by 6-4\sqrt{2}.
