Solution for Log(x+20)-logx=log(x+9) equation:


Simplifying
Log(x + 20) + -1logx = log(x + 9)

Reorder the terms:
goL(20 + x) + -1logx = log(x + 9)
(20 * goL + x * goL) + -1logx = log(x + 9)
(20goL + goxL) + -1logx = log(x + 9)

Reorder the terms:
-1glox + 20goL + goxL = log(x + 9)

Reorder the terms:
-1glox + 20goL + goxL = glo(9 + x)
-1glox + 20goL + goxL = (9 * glo + x * glo)
-1glox + 20goL + goxL = (9glo + glox)

Solving
-1glox + 20goL + goxL = 9glo + glox

Solving for variable 'g'.

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

Add '-9glo' to each side of the equation.
-1glox + 20goL + -9glo + goxL = 9glo + -9glo + glox

Reorder the terms:
-9glo + -1glox + 20goL + goxL = 9glo + -9glo + glox

Combine like terms: 9glo + -9glo = 0
-9glo + -1glox + 20goL + goxL = 0 + glox
-9glo + -1glox + 20goL + goxL = glox

Add '-1glox' to each side of the equation.
-9glo + -1glox + 20goL + -1glox + goxL = glox + -1glox

Reorder the terms:
-9glo + -1glox + -1glox + 20goL + goxL = glox + -1glox

Combine like terms: -1glox + -1glox = -2glox
-9glo + -2glox + 20goL + goxL = glox + -1glox

Combine like terms: glox + -1glox = 0
-9glo + -2glox + 20goL + goxL = 0
