Solution for lg(x)+lg(x)=lg(30x-72)-lg(2) equation:


Simplifying
lg(x) + lg(x) = lg(30x + -72) + -1lg(2)

Multiply gl * x
glx + lg(x) = lg(30x + -72) + -1lg(2)

Multiply gl * x
glx + glx = lg(30x + -72) + -1lg(2)

Combine like terms: glx + glx = 2glx
2glx = lg(30x + -72) + -1lg(2)

Reorder the terms:
2glx = gl(-72 + 30x) + -1lg(2)
2glx = (-72 * gl + 30x * gl) + -1lg(2)
2glx = (-72gl + 30glx) + -1lg(2)

Reorder the terms for easier multiplication:
2glx = -72gl + 30glx + -1 * 2gl

Multiply -1 * 2
2glx = -72gl + 30glx + -2gl

Reorder the terms:
2glx = -72gl + -2gl + 30glx

Combine like terms: -72gl + -2gl = -74gl
2glx = -74gl + 30glx

Solving
2glx = -74gl + 30glx

Solving for variable 'g'.

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

Add '74gl' to each side of the equation.
74gl + 2glx = -74gl + 74gl + 30glx

Combine like terms: -74gl + 74gl = 0
74gl + 2glx = 0 + 30glx
74gl + 2glx = 30glx

Add '-30glx' to each side of the equation.
74gl + 2glx + -30glx = 30glx + -30glx

Combine like terms: 2glx + -30glx = -28glx
74gl + -28glx = 30glx + -30glx

Combine like terms: 30glx + -30glx = 0
74gl + -28glx = 0

Factor out the Greatest Common Factor (GCF), '2gl'.
2gl(37 + -14x) = 0

Ignore the factor 2.

Subproblem 1

Set the factor 'gl' equal to zero and attempt to solve: Simplifying gl = 0 Solving gl = 0 Move all terms containing g to the left, all other terms to the right. Simplifying gl = 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 '(37 + -14x)' equal to zero and attempt to solve: Simplifying 37 + -14x = 0 Solving 37 + -14x = 0 Move all terms containing g to the left, all other terms to the right. Add '-37' to each side of the equation. 37 + -37 + -14x = 0 + -37 Combine like terms: 37 + -37 = 0 0 + -14x = 0 + -37 -14x = 0 + -37 Combine like terms: 0 + -37 = -37 -14x = -37 Add '14x' to each side of the equation. -14x + 14x = -37 + 14x Combine like terms: -14x + 14x = 0 0 = -37 + 14x Simplifying 0 = -37 + 14x 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.
