2-e^x=10e^{-x}-5

Solution

2 - e^{x} = 10 e^{- x} - 5

Solution

x = ln (2), x = ln (5)

+1

Solution steps

2 - e^{x} = 10 e^{- x} - 5

Apply exponent rules

2 - e^{x} = 10 (e^{x})^{- 1} - 5

Rewrite the equation with

e^{x} = u

2 - u = 10 (u)^{- 1} - 5

Solve

2 - u = 10 u^{- 1} - 5 : u = 2, u = 5

u = 2, u = 5

Substitute back

u = e^{x},

solve for

x

Solve

e^{x} = 2 : x = ln (2)

Solve

e^{x} = 5 : x = ln (5)

x = ln (2), x = ln (5)
