141x+93 y =189 .........(i)

93 x + 141 y=45.........(ii)

Add (i) and (ii), we get

141x+93 y =189 

93 x + 141 y=45
_______________
234x + 234 y= 234

x + y=1........ (iii)

Subtract (i) and (ii), we get

141x+93 y =189 

93 x + 141 y=45
_______________
48 x - 48  y=144
  x -  y = 3........ (iv)

Adding (iii) and (iv), we get

    x + y=1
+ x - y = 3

____________

2x = 4
x = 2
Put x = 2 in (iii)
2 + y = 1
y = 1 - 2  = -1
