Solution for y[n]-0.1y[n-1]-0.2y[n-2]=x[n] equation:


Simplifying
y[n] + -0.1y[n + -1] + -0.2y[n + -2] = x[n]

Multiply y * n
ny + -0.1y[n + -1] + -0.2y[n + -2] = x[n]

Reorder the terms:
ny + -0.1y[-1 + n] + -0.2y[n + -2] = x[n]
ny + [-1 * -0.1y + n * -0.1y] + -0.2y[n + -2] = x[n]

Reorder the terms:
ny + [-0.1ny + 0.1y] + -0.2y[n + -2] = x[n]
ny + [-0.1ny + 0.1y] + -0.2y[n + -2] = x[n]

Reorder the terms:
ny + -0.1ny + 0.1y + -0.2y[-2 + n] = x[n]
ny + -0.1ny + 0.1y + [-2 * -0.2y + n * -0.2y] = x[n]

Reorder the terms:
ny + -0.1ny + 0.1y + [-0.2ny + 0.4y] = x[n]
ny + -0.1ny + 0.1y + [-0.2ny + 0.4y] = x[n]

Reorder the terms:
ny + -0.1ny + -0.2ny + 0.1y + 0.4y = x[n]

Combine like terms: ny + -0.1ny = 0.9ny
0.9ny + -0.2ny + 0.1y + 0.4y = x[n]

Combine like terms: 0.9ny + -0.2ny = 0.7ny
0.7ny + 0.1y + 0.4y = x[n]

Combine like terms: 0.1y + 0.4y = 0.5y
0.7ny + 0.5y = x[n]

Multiply x * n
0.7ny + 0.5y = nx

Solving
0.7ny + 0.5y = nx

Solving for variable 'n'.

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

Add '-1nx' to each side of the equation.
0.7ny + -1nx + 0.5y = nx + -1nx

Reorder the terms:
-1nx + 0.7ny + 0.5y = nx + -1nx

Combine like terms: nx + -1nx = 0
-1nx + 0.7ny + 0.5y = 0

Add '-0.5y' to each side of the equation.
-1nx + 0.7ny + 0.5y + -0.5y = 0 + -0.5y

Combine like terms: 0.5y + -0.5y = 0.0
-1nx + 0.7ny + 0.0 = 0 + -0.5y
-1nx + 0.7ny = 0 + -0.5y
Remove the zero:
-1nx + 0.7ny = -0.5y

Combine like terms: -0.5y + 0.5y = 0.0
-1nx + 0.7ny + 0.5y = 0.0

The solution to this equation could not be determined.
