Simplifying 7e2x + 25 = 20 Reorder the terms: 25 + 7e2x = 20 Solving 25 + 7e2x = 20 Solving for variable 'e'. Move all terms containing e to the left, all other terms to the right. Add '-25' to each side of the equation. 25 + -25 + 7e2x = 20 + -25 Combine like terms: 25 + -25 = 0 0 + 7e2x = 20 + -25 7e2x = 20 + -25 Combine like terms: 20 + -25 = -5 7e2x = -5 Divide each side by '7x'. e2 = -0.7142857143x-1 Simplifying e2 = -0.7142857143x-1 Combine like terms: -0.7142857143x-1 + 0.7142857143x-1 = 0.0000000000 e2 + 0.7142857143x-1 = 0.0000000000 Factor out the Greatest Common Factor (GCF), 'x-1'. x-1(e2x + 0.7142857143) = 0.0000000000Subproblem 1
Set the factor 'x-1' equal to zero and attempt to solve: Simplifying x-1 = 0 Solving x-1 = 0 Move all terms containing e to the left, all other terms to the right. Add '-1x-1' to each side of the equation. x-1 + -1x-1 = 0 + -1x-1 Remove the zero: 0 = -1x-1 Simplifying 0 = -1x-1 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 '(e2x + 0.7142857143)' equal to zero and attempt to solve: Simplifying e2x + 0.7142857143 = 0 Reorder the terms: 0.7142857143 + e2x = 0 Solving 0.7142857143 + e2x = 0 Move all terms containing e to the left, all other terms to the right. Add '-0.7142857143' to each side of the equation. 0.7142857143 + -0.7142857143 + e2x = 0 + -0.7142857143 Combine like terms: 0.7142857143 + -0.7142857143 = 0.0000000000 0.0000000000 + e2x = 0 + -0.7142857143 e2x = 0 + -0.7142857143 Combine like terms: 0 + -0.7142857143 = -0.7142857143 e2x = -0.7142857143 Divide each side by 'x'. e2 = -0.7142857143x-1 Simplifying e2 = -0.7142857143x-1 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.
