Answer:

Step-by-step explanation:

141x + 103y=217----------------(1)

103x+141y=27--------------(2)

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

adding 1 and 2 we get...

244x+244y=224-----divide by 224

x+y=1-------(3)

subtracting 2 from 1

141x+103y=217

103x+141y=27

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

38x-38y=190-------divide by 38

x-y=5------(4)

solving (3) and (4)

x+y=1

x-y=5

--------

2x=6

x=6/2

x=3

substituting x=3 in equation (3)

x+y=1

3+y=1

y=1-3

y=-2

hope this helped ;)
