133.9=(133.9)/(1+2e^{-x)}

133.9 = \frac{133.9}{1 + 2 e ^{- x}}

No Solution for x \in R

Solution steps

133.9 = \frac{133.9}{1 + 2 e ^{- x}}

Multiply both sides by

1 + 2 e^{- x}

133.9 (1 + 2 e^{- x}) = \frac{133.9}{1 + 2 e ^{- x}} (1 + 2 e^{- x})

Simplify

133.9 (1 + 2 e^{- x}) = 133.9

Divide both sides by

133.9

1 + 2 e^{- x} = 1

Move

1

to the right side

2 e^{- x} = 0

Divide both sides by

2

e^{- x} = 0

a^{f (x)}

cannot be zero or negative for

x \in R

No Solution for x \in R

3 e^{- 5 x - 8} - 4 = 9

5^{x - 2} - 5^{x} + 5^{x - 1} = 505

2^{x} + 2^{x + 2} = 40

6^{x} - 9 \cdot 6^{- x} + 8 = 0
