Hi there...

Problem...
----------------

------------------------------------------

Nr.1. = 1 burrito and 1 coffee for \$5.60.
Nr.2. = 2 burritos and 3 coffees is \$12.55.
-------------------------------------------------
Determine the cost of one burrito?

-------------------------------------------------

We know the following...

----------------------------
(a+b)=5.60

((2a)+(3b))=12.55

----------------------------

I hope that helped a bit?

Kind regards

1B + 1C = 5.60

2B + 3C = 12.55         two equations, two unknowns......solve for B      Multiply 1st equation by -3 to get:

-3B-3C = -16.8            Now add 2nd and third equations to get:

-B = -4.25

B=4.25                 Done !
