Solution for 2[w-(4w+20)+12]=2(w+8) equation:


Simplifying
2[w + -1(4w + 20) + 12] = 2(w + 8)

Reorder the terms:
2[w + -1(20 + 4w) + 12] = 2(w + 8)
2[w + (20 * -1 + 4w * -1) + 12] = 2(w + 8)
2[w + (-20 + -4w) + 12] = 2(w + 8)

Reorder the terms:
2[-20 + 12 + w + -4w] = 2(w + 8)

Combine like terms: -20 + 12 = -8
2[-8 + w + -4w] = 2(w + 8)

Combine like terms: w + -4w = -3w
2[-8 + -3w] = 2(w + 8)
[-8 * 2 + -3w * 2] = 2(w + 8)
[-16 + -6w] = 2(w + 8)

Reorder the terms:
-16 + -6w = 2(8 + w)
-16 + -6w = (8 * 2 + w * 2)
-16 + -6w = (16 + 2w)

Solving
-16 + -6w = 16 + 2w

Solving for variable 'w'.

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

Add '-2w' to each side of the equation.
-16 + -6w + -2w = 16 + 2w + -2w

Combine like terms: -6w + -2w = -8w
-16 + -8w = 16 + 2w + -2w

Combine like terms: 2w + -2w = 0
-16 + -8w = 16 + 0
-16 + -8w = 16

Add '16' to each side of the equation.
-16 + 16 + -8w = 16 + 16

Combine like terms: -16 + 16 = 0
0 + -8w = 16 + 16
-8w = 16 + 16

Combine like terms: 16 + 16 = 32
-8w = 32

Divide each side by '-8'.
w = -4

Simplifying
w = -4
