You can put this solution on YOUR website! ..........eq.1 ..........eq.2 ..........eq.3
--------------------------------------
start with
..........eq.1.....both sides multiply by ..........eq.2
-------------------------------
..........eq.1 ..........eq.2
---------------------------------subtract eq.2 from eq.1
.......solve for ..........eq.1...both sides multiply by ..........eq.3
------------------------------------- ..........eq.1 ..........eq.3
-------------------------------------subtract eq.3 from eq.1
......solve for .......eq.2a
since eq.1a and eq.2a have same left sides, then right sides are equal too
...........solve for
go to .......eq.2a, substitute for and find
go to ..........eq.1 substitute for , for and find ..........eq.1
