Please help me, please

Answer 1

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
