If it's not what You are looking for type in the equation solver your own equation and let us solve it.
Simplifying F(x) = ln(4x + -20) Multiply F * x xF = ln(4x + -20) Reorder the terms: xF = ln(-20 + 4x) xF = (-20 * ln + 4x * ln) xF = (-20ln + 4lnx) Solving xF = -20ln + 4lnx Solving for variable 'x'. Move all terms containing x to the left, all other terms to the right. Add '-4lnx' to each side of the equation. -4lnx + xF = -20ln + 4lnx + -4lnx Combine like terms: 4lnx + -4lnx = 0 -4lnx + xF = -20ln + 0 -4lnx + xF = -20ln Reorder the terms: 20ln + -4lnx + xF = -20ln + 20ln Combine like terms: -20ln + 20ln = 0 20ln + -4lnx + xF = 0 The solution to this equation could not be determined.
