3ln(2x) + 7 = 15. how do i do this

Step-by-step explanation:

3 ln(2x) + 7 = 15            Subtract 7 from both sides

3 ln(2x)  = 15 - 7            Combine

3 ln(2x) = 8                    Divide by 3

  ln(2x) = 8/3                Do the division. Take the antilog of both sides.

e^ln(2x) = e^(8/3)

2x = 14.392                   Divide by 2

x = 14.392

x = 7. 196

step-by-step explanation:

the multiplicative inverse of a fraction a/b is b/a. for the multiplicative inverse of a real number, divide 1 by the number. for example, the reciprocal of 5 is one fifth 1/5 or 0.2, and the reciprocal of 0.25 is 1 divided by 0.25, or 4.

use formula for the circle a=3.14
