3ln(7x)+7=19

Solution

3 ln (7 x) + 7 = 19

Solution

x = \frac{e ^{4}}{7}

+1

Decimal Notation

x = 7.79973 \dots

Solution steps

3 ln (7 x) + 7 = 19

Move

7

to the right side

3 ln (7 x) = 12

Divide both sides by

3

ln (7 x) = 4

Apply log rules

7 x = e^{4}

Solve

7 x = e^{4} : x = \frac{e ^{4}}{7}

x = \frac{e ^{4}}{7}

Verify Solutions:

x = \frac{e ^{4}}{7}

True

The solution is

x = \frac{e ^{4}}{7}
