Solution for (x+1)-(1-x)=(x-1)-(2-2x) equation:


Simplifying
(x + 1) + -1(1 + -1x) = (x + -1) + -1(2 + -2x)

Reorder the terms:
(1 + x) + -1(1 + -1x) = (x + -1) + -1(2 + -2x)

Remove parenthesis around (1 + x)
1 + x + -1(1 + -1x) = (x + -1) + -1(2 + -2x)
1 + x + (1 * -1 + -1x * -1) = (x + -1) + -1(2 + -2x)
1 + x + (-1 + 1x) = (x + -1) + -1(2 + -2x)

Reorder the terms:
1 + -1 + x + 1x = (x + -1) + -1(2 + -2x)

Combine like terms: 1 + -1 = 0
0 + x + 1x = (x + -1) + -1(2 + -2x)
x + 1x = (x + -1) + -1(2 + -2x)

Combine like terms: x + 1x = 2x
2x = (x + -1) + -1(2 + -2x)

Reorder the terms:
2x = (-1 + x) + -1(2 + -2x)

Remove parenthesis around (-1 + x)
2x = -1 + x + -1(2 + -2x)
2x = -1 + x + (2 * -1 + -2x * -1)
2x = -1 + x + (-2 + 2x)

Reorder the terms:
2x = -1 + -2 + x + 2x

Combine like terms: -1 + -2 = -3
2x = -3 + x + 2x

Combine like terms: x + 2x = 3x
2x = -3 + 3x

Solving
2x = -3 + 3x

Solving for variable 'x'.

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

Add '-3x' to each side of the equation.
