Answer 1

Answer:

Here is your answer ,

__________________

Solution :-

217x+131y=913.....(i)

131x+217y=827.....(ii)

On Adding equation (I) and (ii) , we get :-

348x+348y=1740

x + y = 5...... (iii)

On substracting equation ii from I , we get :-

86x-86y=86

x - y = 1......(iv)

On Solving equation (iii) and (IV) , we get ;

-2y = -4

y = 2

Putting value of y in equation(IV) ,we get ;

X - y = 1

x - 2 = 1

x = 3
