ln(5-x)=2.2

ln (5 - x) = 2.2

x = - e^{2.2} + 5

Decimal Notation

x = - 4.02501 \dots

Solution steps

ln (5 - x) = 2.2

Apply log rules

5 - x = e^{2.2}

Solve

5 - x = e^{2.2} : x = - e^{2.2} + 5

x = - e^{2.2} + 5

\frac{( 2 + lo g _{10} ( x ) )}{( 3 - lo g _{10} ( x ) )} = 5

lo g_{10} (1 - 2 x) = 1

ln (\frac{( x + 6 )}{( x + 2 )}) = ln (x)

lo g_{3} (x) = 1.4

lo g_{2} (x^{2} - 25) - lo g_{2} (x - 5) = 4
