Question

I need to do love for T1 not A or D

Answer 1

`D=kA\left[ \cfrac{T_2 - T_1}{L} \right]\implies D=\cfrac{kA(T_2 - T_1)}{L}\implies DL=kA(T_2 - T_1) \\\\\\ DL=-kA(T_1 - T_2)\implies \cfrac{DL}{-kA}=T_1 - T_2\implies \cfrac{DL}{-kA}+T_2=T_1 \\\\\\ T_2+\cfrac{-DL}{kA}=T_1\implies T_2-\cfrac{DL}{kA}=T_1\implies \cfrac{kAT_2-DL}{kA}=T_1`
