Question

What is the first step to solve m- n = 5 for m?yes

Answer 1

We have the equation m-n=5.

It has 2 unknowns (m and n).

We have to solve it for m:

The first step (and only step in this case) is add n in both sides of the equation:

$\begin{gathered} m-n=5 \\ m-n+n=5+n \\ m=5+n \end{gathered}$
