Answer:

68

_______________________

Step-by-step explanation:

given :

x+y=8

x-y=2

to find:

2x² +2y²

solution:

let,

x+y=8----------(1)

x-y=2-----------(2)

2x² +2y²----------(3)

now,

equation (1)+equation (2)

→ 2x=10

→ x=5

So now substituting value of x in equation(1)

→ 5+y=8

→ y=8-5

→ y=3

now, substituting value of x=5 and y=3  in equation(3)

→ 2(5)² +2(3)²

→ 2(25)+2(9)

→ 50+18

→ 68
