Solution for Log(x)+log(x+7)=log(8) equation:


Simplifying
Log(x) + log(x + 7) = log(8)

Multiply goL * x
goxL + log(x + 7) = log(8)

Reorder the terms:
goxL + glo(7 + x) = log(8)
goxL + (7 * glo + x * glo) = log(8)
goxL + (7glo + glox) = log(8)

Reorder the terms:
7glo + glox + goxL = log(8)

Reorder the terms for easier multiplication:
7glo + glox + goxL = 8glo

Solving
7glo + glox + goxL = 8glo

Solving for variable 'g'.

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

Add '-8glo' to each side of the equation.
7glo + glox + -8glo + goxL = 8glo + -8glo

Reorder the terms:
7glo + -8glo + glox + goxL = 8glo + -8glo

Combine like terms: 7glo + -8glo = -1glo
-1glo + glox + goxL = 8glo + -8glo

Combine like terms: 8glo + -8glo = 0
-1glo + glox + goxL = 0

Factor out the Greatest Common Factor (GCF), 'go'.
go(-1l + lx + xL) = 0

Subproblem 1

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