Question

Solve for x.
4(e^(3x)) + 2 = 22

Answer 1

First subtract 2 from both sides.
Then divide both sides by 4.

Answer 2

That should give you e^(3x) = 5
Take the natural log of both sides.
ln e^(3x) = ln5

Answer 3

4*e^3x=20

e^3x=5
3x=ln5

x=(ln5)/3

Answer 4

\[x=\ln 5 \div 3\]

Answer 5

This gives you 3x = ln5
Divide both sides by 3
x = (ln5)/3

Answer 6

myne looks better... :) lol .. (no offence)
