2x + 5y = 12


We have,


x + y = 3


When y = 0 we have x =3


When x= 0 we have y =3


Thus we have the following table giving points on the line x+y =3



X 0 3

Y 3 0


Now, 2+5y= 12


= y = 12−2x5


When x= 1, we have


= y = 12−2(1)5 = 4


Thus we have the following table giving points on the line 2x+5y=12



X 1 -4

Y 2 4


Graph of the equation x+y =3 and 2x+5y=12 is



1



Clearly two lines intersect at a point P (1,2)


Hence x= 1 and y = 2

The correct value of x is 1 and for y is 2

Thanks
