x = -20 ; y =-5

Step-by-step explanation:

Eqn. 1 ----> 4y = x

Eqn. 2 ----> 5x-10y = -50

(Simplifying eqn.2 further)

=5(x-2y)=-50

$=x-2y=\frac{-50}{5} =-10$

(Substituting the value of x from eqn. 1)

=4y-2y=-10

=2y=-10

$=y =\frac{-10}{2} =-5$

Now, substituting the value of y in eqn. 1 ,

x = 4*(-5)=-20
