Answer:
(x,y)=(-8,-1)
Step-by-step explanation:
(2) rearrange
x=-2+6y
-4(-2+6y)+5y=27
8-24y+5y=27
8-19y=27
-19y=19
y=-1
x=-2+6(-1)
x=-2-6
x=-8
Hope this helps :)
Let's the length to be x,
then the width is 8x - 2.
Perimeter of a rectangle = 2*Width + 2*Length
Perimeter of the rectangle = 2(8x-2) + 2x = 16x - 4 + 2x = 18x - 4
Ar the same time, Perimeter of the rectangle = 88.
So, we can write
18x - 4 = 88
18x = 84
9x=42
x= 42/9 cm (length) or ≈ 4.67 cm (length)
8x - 2 = 8*42/9 - 2 ≈ 35.33 cm (width)
