Solution for lg(2x-1)=2+lgx-lg(x-3) equation:


Simplifying
lg(2x + -1) = 2 + lgx + -1lg(x + -3)

Reorder the terms:
gl(-1 + 2x) = 2 + lgx + -1lg(x + -3)
(-1 * gl + 2x * gl) = 2 + lgx + -1lg(x + -3)
(-1gl + 2glx) = 2 + lgx + -1lg(x + -3)

Reorder the terms:
-1gl + 2glx = 2 + glx + -1gl(-3 + x)
-1gl + 2glx = 2 + glx + (-3 * -1gl + x * -1gl)
-1gl + 2glx = 2 + glx + (3gl + -1glx)

Reorder the terms:
-1gl + 2glx = 2 + 3gl + glx + -1glx

Combine like terms: glx + -1glx = 0
-1gl + 2glx = 2 + 3gl + 0
-1gl + 2glx = 2 + 3gl

Solving
-1gl + 2glx = 2 + 3gl

Solving for variable 'g'.

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

Add '-3gl' to each side of the equation.
-1gl + -3gl + 2glx = 2 + 3gl + -3gl

Combine like terms: -1gl + -3gl = -4gl
-4gl + 2glx = 2 + 3gl + -3gl

Combine like terms: 3gl + -3gl = 0
-4gl + 2glx = 2 + 0
-4gl + 2glx = 2

Reorder the terms:
-2 + -4gl + 2glx = 2 + -2

Combine like terms: 2 + -2 = 0
-2 + -4gl + 2glx = 0

Factor out the Greatest Common Factor (GCF), '2'.
2(-1 + -2gl + glx) = 0

Ignore the factor 2.

Subproblem 1
