Question 1024545
find the values of P_1 and P_2 (where the underscore represents a subscript) 
2P1 -5P2 = -6 
and 
-P1 + 3P2 = 4 
-----------------
Multiply thru the bottom equation by 2 to get:
2P1-5P2 = -6
-2p1+6P2 = 8
---------------
Add and solve for "P2"::
P2 = 2
----
Solve for P1::
P1 = 3P2-4
P1 = 6-4
P1 = 2
-------------
