Answer:
(2,2)
Step-by-step explanation:
first take x-y=0 and multiply it by -5 you will then get this
-5x+5y=0
5x-2y=6
add those together
3y=6
divide by 3
y=2
now plug 2 in for y
x-2=0
add 2 to both sides
x=2

Divide the perimeter by 2, this will give you the sum of one length and one width.
68/2 = 34 yards
Now the length is 10 yards more, so subtract 10 from the 34 and divide by 2 again:
34 - 10 = 24
24 /2 = 12
The width is 12 yards.
The length is 12 + 10 = 22 yards.
