Answer 1

given equations are

10

x

+

5

y

−1=0...(i)×20

And

8

x

+

6

y

=15...(ii)×24

2x+4y=20...(iii)

3x+4y=360...(iv)

2x+4y=20...(iii)

3x+4y=360...(iv)

−−− [ subtracting (iv) from (iii)]

_______________________

−x=−340

⇒4x=+340

now 2x+4y=20 [ from (iii) ]

⇒x+2y=10

⇒340+2y=10[Rsx=340]

⇒2y=10−340

⇒2y=−330

⇒y=

2

−330

=−165

and x=340

Now , y=λx+5 [ given ]

⇒−165=λ(340)+5[Rsy=−165 and x=340]

⇒−λ(340)=170

⇒λ=

−340

170

⇒λ=−

1

hence the solution of the given pair of equation is x=340,y=−165 and λ=−
