Answer:

[tex]n = m - a[/tex]

Step-by-step explanation:

Given

[tex]a = m - n[/tex]

Required

Solve for n

[tex]a = m - n[/tex]

Add n to both sides

[tex]a + n = m - n + n[/tex]

[tex]a + n = m[/tex]

Subtract a from both sides

[tex]a - a + n = m - a[/tex]

[tex]n = m - a[/tex]

Hence, option C answers the question
