Solution for w(w+6)+48=(w+1)(w+7) equation:


Simplifying
w(w + 6) + 48 = (w + 1)(w + 7)

Reorder the terms:
w(6 + w) + 48 = (w + 1)(w + 7)
(6 * w + w * w) + 48 = (w + 1)(w + 7)
(6w + w2) + 48 = (w + 1)(w + 7)

Reorder the terms:
48 + 6w + w2 = (w + 1)(w + 7)

Reorder the terms:
48 + 6w + w2 = (1 + w)(w + 7)

Reorder the terms:
48 + 6w + w2 = (1 + w)(7 + w)

Multiply (1 + w) * (7 + w)
48 + 6w + w2 = (1(7 + w) + w(7 + w))
48 + 6w + w2 = ((7 * 1 + w * 1) + w(7 + w))
48 + 6w + w2 = ((7 + 1w) + w(7 + w))
48 + 6w + w2 = (7 + 1w + (7 * w + w * w))
48 + 6w + w2 = (7 + 1w + (7w + w2))

Combine like terms: 1w + 7w = 8w
48 + 6w + w2 = (7 + 8w + w2)

Add '-1w2' to each side of the equation.
48 + 6w + w2 + -1w2 = 7 + 8w + w2 + -1w2

Combine like terms: w2 + -1w2 = 0
48 + 6w + 0 = 7 + 8w + w2 + -1w2
48 + 6w = 7 + 8w + w2 + -1w2

Combine like terms: w2 + -1w2 = 0
48 + 6w = 7 + 8w + 0
48 + 6w = 7 + 8w

Solving
48 + 6w = 7 + 8w

Solving for variable 'w'.

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

Add '-8w' to each side of the equation.
48 + 6w + -8w = 7 + 8w + -8w

Combine like terms: 6w + -8w = -2w
48 + -2w = 7 + 8w + -8w

Combine like terms: 8w + -8w = 0
48 + -2w = 7 + 0
48 + -2w = 7

Add '-48' to each side of the equation.
48 + -48 + -2w = 7 + -48

Combine like terms: 48 + -48 = 0
0 + -2w = 7 + -48
-2w = 7 + -48

Combine like terms: 7 + -48 = -41
-2w = -41

Divide each side by '-2'.
w = 20.5

Simplifying
w = 20.5
