Question

solve the PLE by elimination method x+y=8 and 2x+y=13
​

Answer 1

Answer:

If x + y = 8 and 2x + y = 13, then the coordinates is (5,3).

Step-by-step explanation:

x + y = 8 ---------- (1)

2x + y = 13 ---------- (2)

Subtract (1) and (2)

   x + y = 8

- 2x + y = 13

-     -      -

____________

-x = -5

x = 5

Put x = 5 in (1), we get

5 + y = 8

y = 8 - 5

y = 3

So, the coordinates is (5,3)
