solvefor x,ln(xy)+4x=45

solve for

x, ln (x y) + 4 x = 45

x = \frac{W ( \frac{4 e ^{45}}{y} )}{4}

Solution steps

ln (x y) + 4 x = 45

Move

4 x

to the right side

ln (x y) = 45 - 4 x

f (x) = g (x),

then

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

e^{l n (x y)} = e^{45 - 4 x}

Simplify

e^{l n (x y)} : x y

x y = e^{45 - 4 x}

Solve

x y = e^{45 - 4 x} : x = \frac{W ( \frac{4 e ^{45}}{y} )}{4}

x = \frac{W ( \frac{4 e ^{45}}{y} )}{4}

Verify Solutions:

x = \frac{W ( \frac{4 e ^{45}}{y} )}{4}

True

The solution is

x = \frac{W ( \frac{4 e ^{45}}{y} )}{4}

20 lo g_{10} (g) = 62.33

lo g_{9} (x) = a \cdot lo g_{3} (x)

lo g_{4} (x + 2) - 1 = - lo g_{4} (x - 1)

x, ln (5 x - 3) = ln (2 x)

lo g_{2} (3 x + 1) + lo g_{2} (x - 3) = 5
