How to solve this eqation?

70=T+c
110=T+ce^(K/2)
145=T+ce^K

solve T = ?wave

Re: How to solve this eqation?

1) First, solve for K using your second equation:



2) Now, note that T=70-c and our K above, use your third equation:

Move over 70, and use that (110-T)/c = (c+40)/c (which you can get from 110=T+c+40 in equation 2)

But e^ln(a)=a, so

Which gives c=-320.


3) So T=70-c=70+320=390.

Bang postponed. Not big enough. Reboot.
