Solution for y(n)=x(n)+5x*(n-1)+4x*(n-2)-4y*(n-1)-4y*(n-2) equation:


Simplifying
y(n) = x(n) + 5x(n + -1) + 4x(n + -2) + -4y(n + -1) + -4y(n + -2)

Multiply y * n
ny = x(n) + 5x(n + -1) + 4x(n + -2) + -4y(n + -1) + -4y(n + -2)

Multiply x * n
ny = nx + 5x(n + -1) + 4x(n + -2) + -4y(n + -1) + -4y(n + -2)

Reorder the terms:
ny = nx + 5x(-1 + n) + 4x(n + -2) + -4y(n + -1) + -4y(n + -2)
ny = nx + (-1 * 5x + n * 5x) + 4x(n + -2) + -4y(n + -1) + -4y(n + -2)

Reorder the terms:
ny = nx + (5nx + -5x) + 4x(n + -2) + -4y(n + -1) + -4y(n + -2)
ny = nx + (5nx + -5x) + 4x(n + -2) + -4y(n + -1) + -4y(n + -2)

Reorder the terms:
ny = nx + 5nx + -5x + 4x(-2 + n) + -4y(n + -1) + -4y(n + -2)
ny = nx + 5nx + -5x + (-2 * 4x + n * 4x) + -4y(n + -1) + -4y(n + -2)

Reorder the terms:
ny = nx + 5nx + -5x + (4nx + -8x) + -4y(n + -1) + -4y(n + -2)
ny = nx + 5nx + -5x + (4nx + -8x) + -4y(n + -1) + -4y(n + -2)

Reorder the terms:
ny = nx + 5nx + -5x + 4nx + -8x + -4y(-1 + n) + -4y(n + -2)
ny = nx + 5nx + -5x + 4nx + -8x + (-1 * -4y + n * -4y) + -4y(n + -2)

Reorder the terms:
ny = nx + 5nx + -5x + 4nx + -8x + (-4ny + 4y) + -4y(n + -2)
ny = nx + 5nx + -5x + 4nx + -8x + (-4ny + 4y) + -4y(n + -2)

Reorder the terms:
ny = nx + 5nx + -5x + 4nx + -8x + -4ny + 4y + -4y(-2 + n)
ny = nx + 5nx + -5x + 4nx + -8x + -4ny + 4y + (-2 * -4y + n * -4y)

Reorder the terms:
ny = nx + 5nx + -5x + 4nx + -8x + -4ny + 4y + (-4ny + 8y)

Reorder the terms:
ny = nx + 5nx + 4nx + -4ny + -4ny + -5x + -8x + 4y + 8y

Combine like terms: nx + 5nx = 6nx
ny = 6nx + 4nx + -4ny + -4ny + -5x + -8x + 4y + 8y

Combine like terms: 6nx + 4nx = 10nx
ny = 10nx + -4ny + -4ny + -5x + -8x + 4y + 8y

Combine like terms: -4ny + -4ny = -8ny
ny = 10nx + -8ny + -5x + -8x + 4y + 8y

Combine like terms: -5x + -8x = -13x
ny = 10nx + -8ny + -13x + 4y + 8y

Combine like terms: 4y + 8y = 12y
ny = 10nx + -8ny + -13x + 12y

Solving
ny = 10nx + -8ny + -13x + 12y

Solving for variable 'n'.

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

Add '-10nx' to each side of the equation.
-10nx + ny = 10nx + -8ny + -13x + -10nx + 12y

Reorder the terms:
-10nx + ny = 10nx + -10nx + -8ny + -13x + 12y

Combine like terms: 10nx + -10nx = 0
-10nx + ny = 0 + -8ny + -13x + 12y
-10nx + ny = -8ny + -13x + 12y

Add '8ny' to each side of the equation.
-10nx + ny + 8ny = -8ny + -13x + 8ny + 12y

Combine like terms: ny + 8ny = 9ny
-10nx + 9ny = -8ny + -13x + 8ny + 12y

Reorder the terms:
-10nx + 9ny = -8ny + 8ny + -13x + 12y

Combine like terms: -8ny + 8ny = 0
-10nx + 9ny = 0 + -13x + 12y
-10nx + 9ny = -13x + 12y

Reorder the terms:
-10nx + 9ny + 13x + -12y = -13x + 13x + 12y + -12y

Combine like terms: -13x + 13x = 0
-10nx + 9ny + 13x + -12y = 0 + 12y + -12y
-10nx + 9ny + 13x + -12y = 12y + -12y

Combine like terms: 12y + -12y = 0
-10nx + 9ny + 13x + -12y = 0
