Question 1011034
Three dozen eggs and five loaves of bread cost $6.90; 
four dozen eggs and two loaves of bread cost $5.70. 
Find the prices for a dozen eggs and for a loaf of bread
-----
3e + 5v = 690 cents
4e + 2v = 570 cents
-------
Modify for elimination::
12e + 20v = 4*690
12e + 6v  = 3*570
------
Subtract and solve for "v"::
14v = 1050
loaf price = 1050/14 = 75 cents
------
Solve for "e"
4e + 2v = 570
4e + 150 = 570
4e = 420
eggs price = 105 cents
