Can someone please show me step by step how to rearrange this equation to get T2? K*((T1-T2)/L)=h(T2-T0) Much appreciated!

HI $\displaystyle k \left(\frac{T_1-T_2}{L}\right) =h(T_2-T_0)$ $\displaystyle \frac{kT_1-kT_2}{L}=T_2h-T_0h$ $\displaystyle kT_1+LT_0h=LT_2h+kT_2$ Bring out $\displaystyle T_2$ so $\displaystyle T_2=\frac{kT_1+LT_0h}{Lh+k}$
Many thanks. I suppose when you think about it it is pretty logical. One more question though. How do you go about bringing out T2? i.e. why does 'Lh+k' become the denominator?
$\displaystyle LT_2h+kT_2$ can be factorised to $\displaystyle T_2(Lh+k)$ so if you divide both sides by $\displaystyle Lh+k$ the $\displaystyle T_2$ will be left on it's own
Where have my maths basics gone. Thanks guys.
