Solution for 2[w-(4w+15)+9]=2(w+6) equation:


Simplifying
2[w + -1(4w + 15) + 9] = 2(w + 6)

Reorder the terms:
2[w + -1(15 + 4w) + 9] = 2(w + 6)
2[w + (15 * -1 + 4w * -1) + 9] = 2(w + 6)
2[w + (-15 + -4w) + 9] = 2(w + 6)

Reorder the terms:
2[-15 + 9 + w + -4w] = 2(w + 6)

Combine like terms: -15 + 9 = -6
2[-6 + w + -4w] = 2(w + 6)

Combine like terms: w + -4w = -3w
2[-6 + -3w] = 2(w + 6)
[-6 * 2 + -3w * 2] = 2(w + 6)
[-12 + -6w] = 2(w + 6)

Reorder the terms:
-12 + -6w = 2(6 + w)
-12 + -6w = (6 * 2 + w * 2)
-12 + -6w = (12 + 2w)

Solving
-12 + -6w = 12 + 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.
-12 + -6w + -2w = 12 + 2w + -2w

Combine like terms: -6w + -2w = -8w
-12 + -8w = 12 + 2w + -2w

Combine like terms: 2w + -2w = 0
-12 + -8w = 12 + 0
-12 + -8w = 12

Add '12' to each side of the equation.
-12 + 12 + -8w = 12 + 12

Combine like terms: -12 + 12 = 0
0 + -8w = 12 + 12
-8w = 12 + 12

Combine like terms: 12 + 12 = 24
-8w = 24

Divide each side by '-8'.
w = -3

Simplifying
