6=2(y-1)

Solution for 6=2(y-1) equation:

Simplifying
6 = 2(y + -1)

Reorder the terms:
6 = 2(-1 + y)
6 = (-1 * 2 + y * 2)
6 = (-2 + 2y)

Solving
6 = -2 + 2y

Solving for variable 'y'.

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

Add '-2y' to each side of the equation.
6 + -2y = -2 + 2y + -2y

Combine like terms: 2y + -2y = 0
