Solution for log(e)(3x+7)=log(e)(x-1) equation:


Simplifying
log(e)(3x + 7) = log(e)(x + -1)

Reorder the terms:
glo * e(7 + 3x) = log(e)(x + -1)

Multiply glo * e
eglo(7 + 3x) = log(e)(x + -1)
(7 * eglo + 3x * eglo) = log(e)(x + -1)
(7eglo + 3eglox) = log(e)(x + -1)

Reorder the terms:
7eglo + 3eglox = glo * e(-1 + x)

Multiply glo * e
7eglo + 3eglox = eglo(-1 + x)
7eglo + 3eglox = (-1 * eglo + x * eglo)
7eglo + 3eglox = (-1eglo + eglox)

Solving
7eglo + 3eglox = -1eglo + eglox

Solving for variable 'e'.

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

Add 'eglo' to each side of the equation.
7eglo + eglo + 3eglox = -1eglo + eglo + eglox

Combine like terms: 7eglo + eglo = 8eglo
8eglo + 3eglox = -1eglo + eglo + eglox

Combine like terms: -1eglo + eglo = 0
8eglo + 3eglox = 0 + eglox
8eglo + 3eglox = eglox

Add '-1eglox' to each side of the equation.
8eglo + 3eglox + -1eglox = eglox + -1eglox

Combine like terms: 3eglox + -1eglox = 2eglox
8eglo + 2eglox = eglox + -1eglox

Combine like terms: eglox + -1eglox = 0
8eglo + 2eglox = 0

Factor out the Greatest Common Factor (GCF), '2eglo'.
2eglo(4 + x) = 0

Ignore the factor 2.

Subproblem 1

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