Answer:
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
Answer:
[tex]\huge \boxed{n=-a+m}[/tex]
Step-by-step explanation:
[tex]a=m-n[/tex]
Adding [tex]n[/tex] to both sides.
[tex]a+n=m-n+n[/tex]
[tex]a+n=m[/tex]
Subtracting [tex]a[/tex] from both sides.
[tex]a+n-a=m-a[/tex]
[tex]n=m-a[/tex]
