Answer:
P = 9
Step-by-step explanation:
To find y :
[2x + 4y = 10] (x1)
[x + 9y = 12] (x2)
--------------------------- -
2x + 4y = 10
2x + 18y = 24
-------------------------- -
4y = 10
18y = 24
-------------------------- -
14 y = 14
y = 1
To find x :
x + 9y = 12
x + 9(1) = 12
x = 12 - 9
x = 3
Put the x and y to find P
P = x + 6y
P = 3 + 6(1)
P = 9
