The answer is " X= 7 and Y = 3 "

Step-by-step explanation:

49X - 57Y = 172 is equation 1

57X - 49Y = 252 is equation 2

equation 1 *-57 = -2793X + 3249Y = -9804

equation 2* 49= 2793X - 2401Y = 12348

adding the two equations = 848Y = 2544

Y = 2544 / 848

Y = 3

substitute the value in equation 1

49X - 57 * 3 = 172

49X = 172 + 171

49X = 343

X = 7
