Hi there...
Problem...
----------------
The "Drive-Through"-menu...:
------------------------------------------
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

+36915 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 !
