Question 739884: I need to find the answer to and show the steps of these two equations but I have no clue what to do.It's part of a project which is a big portion of my grade, any help would be great. The project is i needed to find the milligrams in a collection of broccoli B and corn C 1000 is the calcium needed per day and 8 is the iron per day needed. I need to be able to show both.

The equations are:
133(b)+6(c)=1000
2.07(b)+0.2(c)=8

Answer by Alan3354(69443) (Show Source): You can put this solution on YOUR website!
133(b)+6(c)=1000
2.07(b)+0.2(c)=8
--------------------
Multiply the 2nd eqn by 30
133b + 6c=1000
62.1b+ 6c=240
--------------- Subtract
70.9b = 760
b = 760/709
------------
62.1b+ 6c=240
times 10/3
207b + 20c = 800
c = (800 - 207*760/709)/20
c = 40 - 207*38/709
c = 20494/709
------------
Some ugly fractions.
