Answer 2

Answer:

If x+2y=20 and x-y=5​, then coordinates is (10, 5)

Step-by-step explanation:

x + 2y = 20  -------- (1)

and x-y=5 ​-------- (2)

Subtract (1) and (2)

   x + 2y = 20

-   x - y  = 5

-     +       -

-----------------

    3y = 15

y = 15/3

y = 5

Put y = 5 in (2)

x - 5 = 5

x = 5 + 5

x = 10

So, coordinates is (10,5)
