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.

∴ 
a = 3, b = 4, and c = 2
a + b = c
3 + 4 = 2
3a + 4b = 2c
<u> -4 -4
</u> <u>3a</u> = <u>-6c
</u> 3 3
a = -2
3a + 4b = 2c
<u>-3 -3
</u> <u>4b</u> = <u>-1c</u>
4 4
<h2>
a = 2c/3 - 4b/3</h2>
