6P+3A=390
2P+5A=330 NOW MULTIPLY THIS EQUATION BY -3 & ADD.
----------------------------------------------------
-6P-15A=-990
6P+3A=390
-----------------------
-12A=-600
A=-600/-12
A=50 APPLES. NOW SUBSTITUTE 50 FOR A & SOLVE FOR P
6P+3*50=390
6P+150=390
6P=390-150
6P=240
P=240/6
P=40 NUMBER OF PEARS
PROOF
2*40+5*50=330
80+250=330
330=330
