If 3P+q=14 and P+2Q=12
What is P?
*I'm not sure about the values  |
Theses values are valid
3P+q=14
P+2Q=12
=> P= (14 - q) /3 ______eq I
=> P= 12 - 2Q_________eq II
By subtracting, we get
3P+q=14
P+2Q=12
-----------------
2p+q-2Q = 2
Divinding by 2,we get
=>P+q/2-Q=1
=>P=Q-q/2
=>Q=P+q/2
=>q=2(Q-P)
Any aforementioned value can be find out by putting these in above equation I and II.
