Now,
2x + 3y = 5
x = (5 - 3y)/2 ------ 1.
2x + 7y = 9
x = (9 - 7y)/2 -------2.
Combining eq. 1 and eq. 2
(5 - 3y)/2 = (9 - 7y)/2
or, 2 (5 - 3y) = 2 (9 - 7y)
or, 10 - 6y = 18 - 14y
or, 14y - 6y = 18 - 10
or, 8y = 8
◆ y = 1
putting the value of y in eq. 1,
x = (5 - 3y)/2
= (5 - 3*1)/2
= 2/2
◆ x = 1
I hope you understand...
This is a Right answer...
