Answer: the balance in his check register will be $76 over the balance on his bank account
81.56+n-2.55=0
81.56+n=2.55
n=2.55-81.56
n=-79.01
Area is the space inside a shape
(3, 62)
Since that second equation is equal to y, you can substitute the entire thing into the top equation, getting rid of the y and solving for x. It equals 3.
You can then plug 3 in for x on either equation, which should be 62.
