Question

2. The solution of linear pair of equations 19x + 17y = 55 and 17x + 19y = 53 are

(A) x = 3, y = 2 (B) x = 3, y = -2 (C) x = 2, y = 1 (D) x = 5, y = -3 mcq​

Answer 1

19(3) + 17(2) = 91 and 91 is not equal to 55

19(3) +17(-2) = 23 and 23 is not equal to 55

19(2) + 17(1) = 55 and also 17(2) + 19(1) = 53

So the answer is C.

Hope this helped :)
