Simplifying 42x + 27ln(2x + 1) = 6 Reorder the terms: 42x + 27ln(1 + 2x) = 6 42x + (1 * 27ln + 2x * 27ln) = 6 42x + (27ln + 54lnx) = 6 Reorder the terms: 27ln + 54lnx + 42x = 6 Solving 27ln + 54lnx + 42x = 6 Solving for variable 'l'. Move all terms containing l to the left, all other terms to the right. Add '-42x' to each side of the equation. 27ln + 54lnx + 42x + -42x = 6 + -42x Combine like terms: 42x + -42x = 0 27ln + 54lnx + 0 = 6 + -42x 27ln + 54lnx = 6 + -42x Reorder the terms: -6 + 27ln + 54lnx + 42x = 6 + -42x + -6 + 42x Reorder the terms: -6 + 27ln + 54lnx + 42x = 6 + -6 + -42x + 42x Combine like terms: 6 + -6 = 0 -6 + 27ln + 54lnx + 42x = 0 + -42x + 42x -6 + 27ln + 54lnx + 42x = -42x + 42x Combine like terms: -42x + 42x = 0 -6 + 27ln + 54lnx + 42x = 0 Factor out the Greatest Common Factor (GCF), '3'. 3(-2 + 9ln + 18lnx + 14x) = 0 Ignore the factor 3.Subproblem 1
Set the factor '(-2 + 9ln + 18lnx + 14x)' equal to zero and attempt to solve: Simplifying -2 + 9ln + 18lnx + 14x = 0 Solving -2 + 9ln + 18lnx + 14x = 0 Move all terms containing l to the left, all other terms to the right. Add '2' to each side of the equation. -2 + 9ln + 18lnx + 2 + 14x = 0 + 2 Reorder the terms: -2 + 2 + 9ln + 18lnx + 14x = 0 + 2 Combine like terms: -2 + 2 = 0 0 + 9ln + 18lnx + 14x = 0 + 2 9ln + 18lnx + 14x = 0 + 2 Combine like terms: 0 + 2 = 2 9ln + 18lnx + 14x = 2 Add '-14x' to each side of the equation. 9ln + 18lnx + 14x + -14x = 2 + -14x Combine like terms: 14x + -14x = 0 9ln + 18lnx + 0 = 2 + -14x 9ln + 18lnx = 2 + -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.
