Question

3ln(2x) + 7 = 15. how do I do this
​

Answer 1

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
