Question

7=n+5/2 What is happening to the variable? How do you solve for the variable?

Answer 1

Answer:

the variable is being increased by 5/2

Step-by-step explanation:

7 = n + $\frac{5}{2}$

to solve, you isolate the variable

you can do this by subtracting the $\frac{5}{2}$ from both sides

7 $- \frac{5}{2} = n + \frac{5}{2} - \frac{5}{2}$

the $\frac{5}{2}$ on the right cancels out, leaving you with

$7 -\frac{5}{2} = n$

which simplifies to

$\frac{9}{2} = n$
