Answer:

The  solution is (7, 1).

Step-by-step explanation:

2x - 6y = 8    Multiply this by  -5.

5x - 4y = 31   Multiply this by 2.

-10x + 30y = -40  ...(1)

10x   - 8y = 62.........(2)

Adding (1) and (2):

22y =  22

y = 1.

Substitute for y in the first equation:

2x - 6(1) = 8

2x = 14

x = 7.
