Answer:

x = 3 ,  y = 2

Step-by-step explanation:

217x + 131y = 913...............equation 1

131x  + 217  = 827.................equation 2

adding equation 1 and 2 , we get

348x + 348y = 1740

x+y = 5.............................dividing by 348 ...........equation 3

substracting equation 1 and 2 , we get

86x - 86y  = 86

x-y = 1..........................dividing by 86 ....................equation 4

adding equation 3 and 4, we get

2x = 6

∴ x = 3

putting the value of x in equation 3 , we get

∴ y = 2
