Question

(i) 53x + 97y= 247; 97x + 53y = 203.
​

Answer 1

53x + 97y =247 ....... (1)

97x + 53y =203 ........(2)

Adding (1) and (2)

150x + 150y = 450

Dividing throughout by 150

x + y = 3 ......(3)

Subtracting (2) from (1)

-44x + 44y = 44

-x + y = 1

x - y = -1 .......(4)

Adding (3) and (4)

2x = 2

x = 1

Substituting x = 1 in eq. (3)

1 + y = 3

y = 2

(1,2) is the solution for the given simultaneous equation

Answer 2

answer:- (X,Y) = (1,2)
