pratisthapan Vidhi SE 7 x - 15 y =2 to x+2y=3​

Answer 1

Solution :

7x - 15y = 2 ----( 1 )

x + 2y = 3

=> x = 3 - 2y ---( 2 )

Substitute ( 2 ) in equation

( 1 ) , we get

7(3-2y) - 15y = 2

=> 21 - 14y - 15y = 2

=> -29y = 2 - 21

=> -29y = -19

=> y = -19/-29

=> y = 19/29

Now ,

put y value in equation ( 2 ),

we get

x = 3 - 2(19/29)

=> x = ( 87 - 38 )/29

=> x = 49/29

Therefore

x = 49/29 , y = 19/29
