Solution for 3(2-y)-(-2)(y-2)=-(2y-4) equation:


Simplifying
3(2 + -1y) + -1(-2)(y + -2) = -1(2y + -4)
(2 * 3 + -1y * 3) + -1(-2)(y + -2) = -1(2y + -4)
(6 + -3y) + -1(-2)(y + -2) = -1(2y + -4)

Reorder the terms:
6 + -3y + -1 * -2(-2 + y) = -1(2y + -4)

Multiply -1 * -2
6 + -3y + 2(-2 + y) = -1(2y + -4)
6 + -3y + (-2 * 2 + y * 2) = -1(2y + -4)
6 + -3y + (-4 + 2y) = -1(2y + -4)

Reorder the terms:
6 + -4 + -3y + 2y = -1(2y + -4)

Combine like terms: 6 + -4 = 2
2 + -3y + 2y = -1(2y + -4)

Combine like terms: -3y + 2y = -1y
2 + -1y = -1(2y + -4)

Reorder the terms:
2 + -1y = -1(-4 + 2y)
2 + -1y = (-4 * -1 + 2y * -1)
2 + -1y = (4 + -2y)

Solving
2 + -1y = 4 + -2y
