ln(3x+5)=-1

ln (3 x + 5) = - 1

x = \frac{1 - 5 e}{3 e}

Decimal

x = - 1.54404 \dots

Solution steps

ln (3 x + 5) = - 1

Apply log rules

3 x + 5 = \frac{1}{e}

Solve

3 x + 5 = \frac{1}{e} : x = \frac{1 - 5 e}{3 e}

x = \frac{1 - 5 e}{3 e}

lo g_{19} (x + 7) = 7

- lo g_{10} (x) = 4.55

3 ln (6 x - 3) - 5 = 16

ln (2 x - 1) - ln (x) = 1

51.7 = - 10 lo g_{10} (x)
