Question

solve the system of equations x-7y=8,7x+y=6

Answer 1

Answer:

x-7y=8

7x+y=6... multiply by 7

49x+7y=42

x-7y =8

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

50x= 50

x=1

now we have to find y=

1-7y=8

-7y=8-1

-7Y= 7

Y=-1

Answer 2

Answer:

x-7y=8----(1)

7x+y=6----(2)

(1)×7

7x-49y=56----(3)

(2)-(3)

7x+y-7x+49y=6-56

50y= -50

y= -1

(1)=>

x-7.(-1)=8

x+7=8

x= 1

so, x=1, y= -1
