Solve the equation a=m-n for the variable n.
amid [387]
Our objective is to isolate n one side of the equation. The steps are as follows...

a=m-n
(Add n to both sides)
a+n=m-n+n
(The -n and +n cancel out, on the right side of the equation)
a+n=m
(Now subtract a from both sides)
a+n-a=m+a
(The +a and -a cancel out, on the right side of the equation)
n=m+a
