Answer:
the variable is being increased by 5/2
Step-by-step explanation:
7 = n + [tex]\frac{5}{2}[/tex]
to solve, you isolate the variable
you can do this by subtracting the [tex]\frac{5}{2}[/tex] from both sides
7 [tex]- \frac{5}{2} = n + \frac{5}{2} - \frac{5}{2}[/tex]
the [tex]\frac{5}{2}[/tex] on the right cancels out, leaving you with
[tex]7 -\frac{5}{2} = n[/tex]
which simplifies to
[tex]\frac{9}{2} = n[/tex]
