Solution for in(x+1)+ln(x+3)=ln(x+7) equation:


Simplifying
in(x + 1) + ln(x + 3) = ln(x + 7)

Reorder the terms:
in(1 + x) + ln(x + 3) = ln(x + 7)
(1 * in + x * in) + ln(x + 3) = ln(x + 7)
(1in + inx) + ln(x + 3) = ln(x + 7)

Reorder the terms:
1in + inx + ln(3 + x) = ln(x + 7)
1in + inx + (3 * ln + x * ln) = ln(x + 7)
1in + inx + (3ln + lnx) = ln(x + 7)

Reorder the terms:
1in + inx + 3ln + lnx = ln(7 + x)
1in + inx + 3ln + lnx = (7 * ln + x * ln)
1in + inx + 3ln + lnx = (7ln + lnx)

Add '-1lnx' to each side of the equation.
1in + inx + 3ln + lnx + -1lnx = 7ln + lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
1in + inx + 3ln + 0 = 7ln + lnx + -1lnx
1in + inx + 3ln = 7ln + lnx + -1lnx

Combine like terms: lnx + -1lnx = 0
1in + inx + 3ln = 7ln + 0
1in + inx + 3ln = 7ln

Solving
1in + inx + 3ln = 7ln

Solving for variable 'i'.

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

Add '-3ln' to each side of the equation.
1in + inx + 3ln + -3ln = 7ln + -3ln

Combine like terms: 3ln + -3ln = 0
1in + inx + 0 = 7ln + -3ln
1in + inx = 7ln + -3ln

Combine like terms: 7ln + -3ln = 4ln
1in + inx = 4ln

Combine like terms: 4ln + -4ln = 0
1in + inx + -4ln = 0

Factor out the Greatest Common Factor (GCF), 'n'.
n(i + ix + -4l) = 0

Subproblem 1

Set the factor 'n' equal to zero and attempt to solve: Simplifying n = 0 Solving n = 0 Move all terms containing i to the left, all other terms to the right. Add '-1n' to each side of the equation. n + -1n = 0 + -1n Remove the zero: 0 = -1n Simplifying 0 = -1n 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 '(i + ix + -4l)' equal to zero and attempt to solve: Simplifying i + ix + -4l = 0 Solving i + ix + -4l = 0 Move all terms containing i to the left, all other terms to the right. Add '4l' to each side of the equation. i + ix + -4l + 4l = 0 + 4l Combine like terms: -4l + 4l = 0 i + ix + 0 = 0 + 4l i + ix = 0 + 4l Remove the zero: i + ix = 4l 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.
