First, set up an equation that models this statement.
N is your variable because it’s the unknown Number.
8n-13=43
Then, add 13 on both sides so you have the variable and it’s coefficient alone.
8n-13=43
+13.+13
________
8n=56
Then, divide the variable and the coefficient by the coefficient.
8n=56
—. —
8. 8
Now you have your variable all by itself, and you have the persons number.
n=7
Your number is 7.
