ln(x)=7-x

Solution

ln (x) = 7 - x

Solution

x = W_{0} (e^{7})

+1

Decimal Notation

x = 5.32717 \dots

Solution steps

ln (x) = 7 - x

If

f (x) = g (x),

then

a^{f (x)} = a^{g (x)}

e^{l n (x)} = e^{7 - x}

Simplify

e^{l n (x)} : x

x = e^{7 - x}

Solve

x = e^{7 - x} : x = W_{0} (e^{7})

x = W_{0} (e^{7})

Verify Solutions:

x = W_{0} (e^{7})

True

The solution is

x = W_{0} (e^{7})

Popular Examples

lo g_{4} (2 x) = 2

2 ln (b) = ln (b^{2})

log_{10}(x)+log_{10}(x+1)=4

lo g_{10} (x) + lo g_{10} (x + 1) = 4

log_{10}(x)+log_{10}(x+1)=7

lo g_{10} (x) + lo g_{10} (x + 1) = 7

log_{10}(x)+log_{10}(x+1)=6

lo g_{10} (x) + lo g_{10} (x + 1) = 6
