With an algebraic equation like this, it's helpful to isolate the terms with variables (in this case n/4) on the left side of the equation and the constant terms (numbers) on the right side.

-9 + n/4 = -7

Add 9 to both sides:

-9 + 9 + n/4 = -7 + 9

n/4 = 2

Now isolate the variable n by multiplying both sides by 4:

4(n/4) = 2 * 4

n = 8

 

Hope that helps!

-9 + n/4 = -7

-9 + 9 + n/4 = -7 + 9

n/4 = 2

4 * (n/4) = 4 * 2

n = 8
