Simplifying lny = lnx + ln(x + 20) + lnc Reorder the terms: lny = lnx + ln(20 + x) + lnc lny = lnx + (20 * ln + x * ln) + lnc lny = lnx + (20ln + lnx) + lnc Reorder the terms: lny = cln + 20ln + lnx + lnx Combine like terms: lnx + lnx = 2lnx lny = cln + 20ln + 2lnx Solving lny = cln + 20ln + 2lnx Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-1cln' to each side of the equation. -1cln + lny = cln + 20ln + -1cln + 2lnx Reorder the terms: -1cln + lny = cln + -1cln + 20ln + 2lnx Combine like terms: cln + -1cln = 0 -1cln + lny = 0 + 20ln + 2lnx -1cln + lny = 20ln + 2lnx Add '-20ln' to each side of the equation. -1cln + -20ln + lny = 20ln + -20ln + 2lnx Combine like terms: 20ln + -20ln = 0 -1cln + -20ln + lny = 0 + 2lnx -1cln + -20ln + lny = 2lnx Add '-2lnx' to each side of the equation. -1cln + -20ln + -2lnx + lny = 2lnx + -2lnx Combine like terms: 2lnx + -2lnx = 0 -1cln + -20ln + -2lnx + lny = 0 Factor out the Greatest Common Factor (GCF), 'ln'. ln(-1c + -20 + -2x + y) = 0Subproblem 1
Set the factor 'ln' equal to zero and attempt to solve: Simplifying ln = 0 Solving ln = 0 Move all terms containing l to the left, all other terms to the right. Simplifying ln = 0 The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Subproblem 2
Set the factor '(-1c + -20 + -2x + y)' equal to zero and attempt to solve: Simplifying -1c + -20 + -2x + y = 0 Reorder the terms: -20 + -1c + -2x + y = 0 Solving -20 + -1c + -2x + y = 0 Move all terms containing l to the left, all other terms to the right. Add '20' to each side of the equation. -20 + -1c + -2x + 20 + y = 0 + 20 Reorder the terms: -20 + 20 + -1c + -2x + y = 0 + 20 Combine like terms: -20 + 20 = 0 0 + -1c + -2x + y = 0 + 20 -1c + -2x + y = 0 + 20 Combine like terms: 0 + 20 = 20 -1c + -2x + y = 20 Add 'c' to each side of the equation. -1c + -2x + c + y = 20 + c Reorder the terms: -1c + c + -2x + y = 20 + c Combine like terms: -1c + c = 0 0 + -2x + y = 20 + c -2x + y = 20 + c Add '2x' to each side of the equation. -2x + 2x + y = 20 + c + 2x Combine like terms: -2x + 2x = 0 0 + y = 20 + c + 2x y = 20 + c + 2x Add '-1y' to each side of the equation. y + -1y = 20 + c + 2x + -1y Combine like terms: y + -1y = 0 0 = 20 + c + 2x + -1y Simplifying 0 = 20 + c + 2x + -1y The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
