Solution for y[n]=0.5x[n]+0.5y[n-1] equation:


Simplifying
y[n] = 0.5x[n] + 0.5y[n + -1]

Multiply y * n
ny = 0.5x[n] + 0.5y[n + -1]

Multiply x * n
ny = 0.5nx + 0.5y[n + -1]

Reorder the terms:
ny = 0.5nx + 0.5y[-1 + n]
ny = 0.5nx + [-1 * 0.5y + n * 0.5y]

Reorder the terms:
ny = 0.5nx + [0.5ny + -0.5y]
ny = 0.5nx + [0.5ny + -0.5y]

Solving
ny = 0.5nx + 0.5ny + -0.5y

Solving for variable 'n'.

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

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

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

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

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

Combine like terms: ny + -0.5ny = 0.5ny
-0.5nx + 0.5ny = 0.5ny + -0.5ny + -0.5y

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

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