J=(T-M)/D

Explanation:

M+DJ=T

The idea is to get J on the left and all the other stuff to the right

Let's move M to the right. To do that let's subtract M from both sides
\cancelM+DJ\cancelcolor(blue)(-M)=T\color(blue)(-M)

And we get
DJ=T-M

To reach our objective we can divide both sides by D
(\cancel(D)J)/color(red)cancel(D)=(T-M)/\color(red)D

And the solution is:
J=(T-M)/D
