2x + (y + x) = 180 [Supplementary angles]
2x + y + x = 180
3x + y = 180 ---------- (1)
(y + x) + (y - x) = 180 [Supplementary angles]
y + x + y - x = 180
2y = 180
y = 90 --------------- sub into (1)
3x + 90 = 180
3x = 90
x = 30
Ans: x = 30, y = 90

Answer:
Cost of rug during sale = $140
Step-by-step explanation:
Given
Marked price of rug in a store = $200
The store is holding a sale and offering a flat 30% less on marked price on all items
This means the sale price of all items would decrease by 30%
We can calculate the discount offered by taking out percentage discount of the marked price.
Discount offered on rug = 30% of Marked price 
The discount is then subtracted from the marked price to get the price of rug during sale.
∴ Price of rug during sale = Marked price - Discount
