Answer:
Answer:
p = 5/3
Step-by-step explanation:
4/x + 6y = 10 -------(1)
1/x - 6y = 5 --------(2)
using elimination method
on adding eq 1 and 2
4/x + 6y = 10
1/x - 6y = 5
4/x + 1/x = 15
(4+1)/x = 15
5/x = 15
5 = 15x
5/15 = x
1/3 = x
put x in eq 1
4(1/3) + 6y = 10
4/3 + 6y = 10
6y = 10 - 4/3
6y = (30 - 4)/3
6y = 26/3
y = 26/3 × 6
y = 156/3
y = 52
value of p
p = 5x
put x = 1/3
p = 5 × 1/3
p = 5/3
