plz answer this question​

Answer 1

Answer:

x = -8

y = -2

perimeter = -76

Step-by-step explanation:

2x + y + 8 = 4x - y

i.e 8 = 2x - 2y

i.e. 8 = 2(x - y)

i.e 4 = x- y

i.e x = 4y eq(1)

2y = x + 4. put eq(1)

2y = 4y + 4

2y - 4y = 4

-2y = 4

y = -2

Now put y in eq(1)

x = 4(-2)

x= -8

Now

perimeter = 2( L+ B)

= 2 {(4x - y)+(2y)}

= 2{( -32-2)+(-4)}

= 2{(-34)-4} = 2(-38)= -76 units

Answer 2

Step-by-step explanation:

the value of X=12 and the value of Y = 8
