Okay, this is my proof. I'm not exactly sure if this is a viable proof, but I think it works.


Hence, from x > 0, it is always increasing (gradient > 0)
y = lnx crosses the x-axis only once, so there is only one root.
Since x cannot be less than zero, as well as a monotonic increasing function for x > 0, and the fact that it crosses the x-axis once, then as x approaches 0 from the positive side, f(x) has to be approaching negative infinity.
100/2 = 50
I think the answer is 50.
I hope this helps! :D
<h2><u>The value of x is equal to 6.</u></h2>
2 + 3x = 20
Subtract 2 from both sides.
3x = 18
Divide both sides by 3.
x = 6
