Question 837957: i need to see step-by-step solutions to solve this equation by graphing
Bob ate 10 carrots and 7 Hershey’s kisses and the total calories were 263. Fred ate 4 carrots and 8 Hershey’s kisses and the total calories were 230. How many calories are in a carrot and a Hershey’s kiss? (The answer is not a scientific truth, only made up numbers!!!)
i would like to see all the work shown and the graph that was used to solve please
and if you could chat with me and kinda explain how you did it would be greatly appreciated

You can put this solution on YOUR website! Bob ate 10 carrots and 7 Hershey’s kisses and the total calories were 263. Fred ate 4 carrots and 8 Hershey’s kisses and the total calories were 230. How many calories are in a carrot and a Hershey’s kiss?
-------
Equation:
10c + 7h = 263
4c + 8h = 230
=======
Modify for elimination::
40c + 28h = 4*263
40c + 80h = 2300
-----------------------
Subtract and solve for "h":
52h = 1248
h = 24 (# of hershey kisses)
-----------------
Solve for "c":
4c + 8h = 230
c + 2h = 115
c = 115-2*24
c = 67 (# of carrots)
========================
