Ok so for a problem where you solve for a variable, you have to get the variable on one side of the equal sign by itself. To do this you have to do the opposite of what the question asks

n = 17 

you just have to subtract 13 from 30

squidnnneyyy · Answer

Since it says n+13, you do the opposite of addition

But guys plz don't have me get it wrong my mom says I need a 120% on extra credit

squidnnneyyy · Answer

The opposite of addition is subtraction so you subtract 13 from both sides.

n+13=30
-13     -13      When you subtract 13 is canceled out so you have
n=30-13.        30-13 is 17.
n=17
