Answer 2

Answer:

I think there is a small mistake 134 is 13y

Step-by-step explanation:

13x+12y=21....(1)

12x+13y=29...(2)

(1)+(2)

13x+12x+12y+13y=21+29

25x+25y=50

x+y=2.....(3)

(2)-(1)

12x-13x+13y-12y=29-21

-x+y=8

x-y=8....(4)

(3)+(4)

x+x+y-y=2+8

2x=10

x=5

put x value

5-y=8

-y=8-5

y=-8+5

y=-3

X=5, y=-3
