# How do you solve for J in M+DJ=T?

Mar 25, 2018

$J = \frac{T - M}{D}$

#### Explanation:

$M + D J = T$

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
$\setminus \cancel{M} + D J \setminus \cancel{\textcolor{b l u e}{- M}} = T \setminus \textcolor{b l u e}{- M}$

And we get
$D J = T - M$

To reach our objective we can divide both sides by $D$
$\frac{\setminus \cancel{D} J}{\textcolor{red}{\cancel{D}}} = \frac{T - M}{\setminus} \textcolor{red}{D}$

And the solution is:
$J = \frac{T - M}{D}$
