Heya !!!
49X - 57Y = 172 ---------(1)
And,
57X - 49Y = 252 ----------(2)
From equation (1) we get,
49X - 57Y = 172
49X = 172+57Y
X = (172+57Y/49) --------(3)
Putting the value of X in equation (2)
57X - 49Y = 252
57 × ( 172+57Y/49) - 49Y = 252
57 × 172 + 57 × 57Y/49 - 49Y = 252
9804 + 3249Y/49 - 49Y = 252
9804 + 3249Y - 2401Y = 252 × 49
848Y + 9804 = 12348
848Y = 12348-9804
848Y = 2544
Y = 2544/848
Y = 3
Putting the value of Y in equation (3)
X = 172+57Y/49
X = 172 + 57 × 3/49
X = 172+171/49 = 343/49
X = 7
Hence,
X = 7 and Y= 3
