Reorder the terms:
(11 + 11y)(11y + -11) = 0

Reorder the terms:
(11 + 11y)(-11 + 11y) = 0

Multiply (11 + 11y) * (-11 + 11y)
(11(-11 + 11y) + 11y * (-11 + 11y)) = 0
((-11 * 11 + 11y * 11) + 11y * (-11 + 11y)) = 0
((-121 + 121y) + 11y * (-11 + 11y)) = 0
(-121 + 121y + (-11 * 11y + 11y * 11y)) = 0
(-121 + 121y + (-121y + 121y2)) = 0

Combine like terms: 121y + -121y = 0
(-121 + 0 + 121y2) = 0
(-121 + 121y2) = 0

Solving
-121 + 121y2 = 0

Solving for variable 'y'.

Move all terms containing y to the left, all other terms to the right.
