b(x)=ln(x)-4

Solution

b (x) = ln (x) - 4

Solution

x = - \frac{W ( - e ^{4} b )}{b}

Solution steps

b (x) = ln (x) - 4

Switch sides

ln (x) - 4 = b x

Move

4

to the right side

ln (x) = b x + 4

If

f (x) = g (x),

then

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

e^{l n (x)} = e^{b x + 4}

Simplify

e^{l n (x)} : x

x = e^{b x + 4}

Solve

x = e^{b x + 4} : x = - \frac{W ( - e ^{4} b )}{b}

x = - \frac{W ( - e ^{4} b )}{b}

Verify Solutions:

x = - \frac{W ( - e ^{4} b )}{b}

True

The solution is

x = - \frac{W ( - e ^{4} b )}{b}
