Solution for lg(3x-5)=lg(4-x) equation:


Simplifying
lg(3x + -5) = lg(4 + -1x)

Reorder the terms:
gl(-5 + 3x) = lg(4 + -1x)
(-5 * gl + 3x * gl) = lg(4 + -1x)
(-5gl + 3glx) = lg(4 + -1x)
-5gl + 3glx = (4 * gl + -1x * gl)
-5gl + 3glx = (4gl + -1glx)

Solving
-5gl + 3glx = 4gl + -1glx

Solving for variable 'g'.

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

Add '-4gl' to each side of the equation.
-5gl + -4gl + 3glx = 4gl + -4gl + -1glx

Combine like terms: -5gl + -4gl = -9gl
-9gl + 3glx = 4gl + -4gl + -1glx

Combine like terms: 4gl + -4gl = 0
-9gl + 3glx = 0 + -1glx
-9gl + 3glx = -1glx

Add 'glx' to each side of the equation.
-9gl + 3glx + glx = -1glx + glx

Combine like terms: 3glx + glx = 4glx
-9gl + 4glx = -1glx + glx

Combine like terms: -1glx + glx = 0
-9gl + 4glx = 0
