Anyone here a math genius? - Page 2

This is what I got

y^x=3y-1

x= (ln(3y-1)/ln(y)) only if y > 1/3

z=3^x+5

z = (3y-1)^(ln(3)/ln(y))+5

So basically we have two equations and 3 unknowns.

What's wrong with my answer?

because without more info there is infinite solutions.

Well the fact that we start with two variables, and only one complete equation means that you cant solve for both variables.

Aw shucks...

I really want this to be

yx=3y-1 solve for 3x+5

y=1
x=2

solution=11

Every now and again I like to look in these threads to make myself feel dumb. Success.

Yea I know... I still think that this is some kind of misprint or something...

Same here

There's a reason I was an English major

Sounds like you need to get more info from her before any of us can solve it.

Hey, I've solved it twice!
