Solution for -2(w-7)-(1-w)=2(1+w)+w-3 equation:


Simplifying
-2(w + -7) + -1(1 + -1w) = 2(1 + w) + w + -3

Reorder the terms:
-2(-7 + w) + -1(1 + -1w) = 2(1 + w) + w + -3
(-7 * -2 + w * -2) + -1(1 + -1w) = 2(1 + w) + w + -3
(14 + -2w) + -1(1 + -1w) = 2(1 + w) + w + -3
14 + -2w + (1 * -1 + -1w * -1) = 2(1 + w) + w + -3
14 + -2w + (-1 + 1w) = 2(1 + w) + w + -3

Reorder the terms:
14 + -1 + -2w + 1w = 2(1 + w) + w + -3

Combine like terms: 14 + -1 = 13
13 + -2w + 1w = 2(1 + w) + w + -3

Combine like terms: -2w + 1w = -1w
13 + -1w = 2(1 + w) + w + -3
13 + -1w = (1 * 2 + w * 2) + w + -3
13 + -1w = (2 + 2w) + w + -3

Reorder the terms:
13 + -1w = 2 + -3 + 2w + w

Combine like terms: 2 + -3 = -1
13 + -1w = -1 + 2w + w

Combine like terms: 2w + w = 3w
13 + -1w = -1 + 3w

Solving
13 + -1w = -1 + 3w

Solving for variable 'w'.

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

Add '-3w' to each side of the equation.
13 + -1w + -3w = -1 + 3w + -3w

Combine like terms: -1w + -3w = -4w
13 + -4w = -1 + 3w + -3w

Combine like terms: 3w + -3w = 0
13 + -4w = -1 + 0
13 + -4w = -1

Add '-13' to each side of the equation.
13 + -13 + -4w = -1 + -13

Combine like terms: 13 + -13 = 0
0 + -4w = -1 + -13
-4w = -1 + -13

Combine like terms: -1 + -13 = -14
-4w = -14

Divide each side by '-4'.
w = 3.5

Simplifying
w = 3.5
