Solution for 2n(n+4)+18=n(n+5)+n(n-2-7) equation:


Simplifying
2n(n + 4) + 18 = n(n + 5) + n(n + -2 + -7)

Reorder the terms:
2n(4 + n) + 18 = n(n + 5) + n(n + -2 + -7)
(4 * 2n + n * 2n) + 18 = n(n + 5) + n(n + -2 + -7)
(8n + 2n2) + 18 = n(n + 5) + n(n + -2 + -7)

Reorder the terms:
18 + 8n + 2n2 = n(n + 5) + n(n + -2 + -7)

Reorder the terms:
18 + 8n + 2n2 = n(5 + n) + n(n + -2 + -7)
18 + 8n + 2n2 = (5 * n + n * n) + n(n + -2 + -7)
18 + 8n + 2n2 = (5n + n2) + n(n + -2 + -7)

Reorder the terms:
18 + 8n + 2n2 = 5n + n2 + n(-2 + -7 + n)

Combine like terms: -2 + -7 = -9
18 + 8n + 2n2 = 5n + n2 + n(-9 + n)
18 + 8n + 2n2 = 5n + n2 + (-9 * n + n * n)
18 + 8n + 2n2 = 5n + n2 + (-9n + n2)

Reorder the terms:
18 + 8n + 2n2 = 5n + -9n + n2 + n2

Combine like terms: 5n + -9n = -4n
18 + 8n + 2n2 = -4n + n2 + n2

Combine like terms: n2 + n2 = 2n2
18 + 8n + 2n2 = -4n + 2n2

Add '-2n2' to each side of the equation.
18 + 8n + 2n2 + -2n2 = -4n + 2n2 + -2n2

Combine like terms: 2n2 + -2n2 = 0
18 + 8n + 0 = -4n + 2n2 + -2n2
18 + 8n = -4n + 2n2 + -2n2

Combine like terms: 2n2 + -2n2 = 0
18 + 8n = -4n + 0
18 + 8n = -4n

Solving
18 + 8n = -4n

Solving for variable 'n'.

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

Add '4n' to each side of the equation.
18 + 8n + 4n = -4n + 4n

Combine like terms: 8n + 4n = 12n
18 + 12n = -4n + 4n

Combine like terms: -4n + 4n = 0
18 + 12n = 0

Add '-18' to each side of the equation.
18 + -18 + 12n = 0 + -18

Combine like terms: 18 + -18 = 0
0 + 12n = 0 + -18
12n = 0 + -18

Combine like terms: 0 + -18 = -18
12n = -18

Divide each side by '12'.
n = -1.5

Simplifying
n = -1.5
