Answer
Solution:
p = 79
n = 52
Step-by-step explanation:
Given equations:
A) 
B) 
To solve for 
and 
Naming the first equation as A and second as B.
Using elimination method to solve.
In order to eliminate we subtract equation A from B.
Subtracting A from B i.e [
(B)
- (A)
We get, 
Dividing both sides 2.26.
∴ 
We can solve for by substituting in equation A.
Subtracting both sides by 52.
∴
