Simplifying y(n) + 0.1y(n + -1) + -0.2y(n + -2) = x(n) + x(n + -1) Multiply y * n ny + 0.1y(n + -1) + -0.2y(n + -2) = x(n) + x(n + -1) Reorder the terms: ny + 0.1y(-1 + n) + -0.2y(n + -2) = x(n) + x(n + -1) ny + (-1 * 0.1y + n * 0.1y) + -0.2y(n + -2) = x(n) + x(n + -1) Reorder the terms: ny + (0.1ny + -0.1y) + -0.2y(n + -2) = x(n) + x(n + -1) ny + (0.1ny + -0.1y) + -0.2y(n + -2) = x(n) + x(n + -1) Reorder the terms: ny + 0.1ny + -0.1y + -0.2y(-2 + n) = x(n) + x(n + -1) ny + 0.1ny + -0.1y + (-2 * -0.2y + n * -0.2y) = x(n) + x(n + -1) Reorder the terms: ny + 0.1ny + -0.1y + (-0.2ny + 0.4y) = x(n) + x(n + -1) ny + 0.1ny + -0.1y + (-0.2ny + 0.4y) = x(n) + x(n + -1) Reorder the terms: ny + 0.1ny + -0.2ny + -0.1y + 0.4y = x(n) + x(n + -1) Combine like terms: ny + 0.1ny = 1.1ny 1.1ny + -0.2ny + -0.1y + 0.4y = x(n) + x(n + -1) Combine like terms: 1.1ny + -0.2ny = 0.9ny 0.9ny + -0.1y + 0.4y = x(n) + x(n + -1) Combine like terms: -0.1y + 0.4y = 0.3y 0.9ny + 0.3y = x(n) + x(n + -1) Multiply x * n 0.9ny + 0.3y = nx + x(n + -1) Reorder the terms: 0.9ny + 0.3y = nx + x(-1 + n) 0.9ny + 0.3y = nx + (-1 * x + n * x) Reorder the terms: 0.9ny + 0.3y = nx + (nx + -1x) 0.9ny + 0.3y = nx + (nx + -1x) Combine like terms: nx + nx = 2nx 0.9ny + 0.3y = 2nx + -1x Solving 0.9ny + 0.3y = 2nx + -1x Solving for variable 'n'. Move all terms containing n to the left, all other terms to the right. Add '-2nx' to each side of the equation. 0.9ny + -2nx + 0.3y = 2nx + -2nx + -1x Reorder the terms: -2nx + 0.9ny + 0.3y = 2nx + -2nx + -1x Combine like terms: 2nx + -2nx = 0 -2nx + 0.9ny + 0.3y = 0 + -1x -2nx + 0.9ny + 0.3y = -1x Add '-0.3y' to each side of the equation. -2nx + 0.9ny + 0.3y + -0.3y = -1x + -0.3y Combine like terms: 0.3y + -0.3y = 0.0 -2nx + 0.9ny + 0.0 = -1x + -0.3y -2nx + 0.9ny = -1x + -0.3y Reorder the terms: -2nx + 0.9ny + x + 0.3y = -1x + x + -0.3y + 0.3y Combine like terms: -1x + x = 0 -2nx + 0.9ny + x + 0.3y = 0 + -0.3y + 0.3y -2nx + 0.9ny + x + 0.3y = -0.3y + 0.3y Combine like terms: -0.3y + 0.3y = 0.0 -2nx + 0.9ny + x + 0.3y = 0.0 The solution to this equation could not be determined.
