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


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

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

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

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

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

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

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

Combine like terms: 2ny + -1ny = 1ny
1ny + ny + 1y + -2y = x[n]

Combine like terms: 1ny + ny = 2ny
2ny + 1y + -2y = x[n]

Combine like terms: 1y + -2y = -1y
2ny + -1y = x[n]

Multiply x * n
2ny + -1y = nx

Solving
2ny + -1y = 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.
2ny + -1nx + -1y = nx + -1nx

Reorder the terms:
-1nx + 2ny + -1y = nx + -1nx

Combine like terms: nx + -1nx = 0
-1nx + 2ny + -1y = 0

Add 'y' to each side of the equation.
-1nx + 2ny + -1y + y = 0 + y

Combine like terms: -1y + y = 0
-1nx + 2ny + 0 = 0 + y
-1nx + 2ny = 0 + y
Remove the zero:
-1nx + 2ny = y

Combine like terms: y + -1y = 0
-1nx + 2ny + -1y = 0
