Answer 1

Answer:

plz write you question properly

Step-by-step explanation:

(8) 49x – 57y = 172                         .....(I)

57x – 49y = 252                              .....(II)

Adding (I) and (II)  

49x+57x-57y-49y=172+252⇒106x-106y=424⇒x-y=4                                            .....III

Subtracting (II) from (I) we have

49x-57y-57y--49y=252-172⇒-8x-8y=-80⇒-x-y=-10                                         ⇒x+y=10                                      .....IV

Adding (III) and (IV)

x-y=4x+y=10⇒2x=14⇒x=7

Putting the value of x = 7 in (IV) we get

7+y=10⇒y=10-7⇒y=3

Thus, (x, y) = (7, 3).
