Answer:

(6 , 1)

Step-by-step explanation:

x - 5y =1         (1)

2x + 5y = 17  (2)

(1) + (2) ⇒ 3x = 1 + 17

           ⇒ 3x = 18

           ⇒ x = 6

now, we just replace x by 6 in equation (1) ⇒ 6 - 5y =1 ⇒ y = 1

Answer:

(6, 1).

Step-by-step explanation:

x - 5y =1

2x + 5y = 17    Adding the 2 equations eliminates the  term in y:

3x  + 0 = 18

x = 6.

Plug x = 6 into the first equation:

6 - 5y = 1

-5y = -5

y = 1.
