Simplifying 5e2x + 7 = 21 Reorder the terms: 7 + 5e2x = 21 Solving 7 + 5e2x = 21 Solving for variable 'e'. Move all terms containing e to the left, all other terms to the right. Add '-7' to each side of the equation. 7 + -7 + 5e2x = 21 + -7 Combine like terms: 7 + -7 = 0 0 + 5e2x = 21 + -7 5e2x = 21 + -7 Combine like terms: 21 + -7 = 14 5e2x = 14 Divide each side by '5x'. e2 = 2.8x-1 Simplifying e2 = 2.8x-1 Combine like terms: 2.8x-1 + -2.8x-1 = 0.0 e2 + -2.8x-1 = 0.0 Factor out the Greatest Common Factor (GCF), 'x-1'. x-1(e2x + -2.8) = 0.0Subproblem 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 + -2.8)' equal to zero and attempt to solve: Simplifying e2x + -2.8 = 0 Reorder the terms: -2.8 + e2x = 0 Solving -2.8 + e2x = 0 Move all terms containing e to the left, all other terms to the right. Add '2.8' to each side of the equation. -2.8 + 2.8 + e2x = 0 + 2.8 Combine like terms: -2.8 + 2.8 = 0.0 0.0 + e2x = 0 + 2.8 e2x = 0 + 2.8 Combine like terms: 0 + 2.8 = 2.8 e2x = 2.8 Divide each side by 'x'. e2 = 2.8x-1 Simplifying e2 = 2.8x-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.
