Answer:
[tex]x = -20 ; y =-5[/tex]
Step-by-step explanation:
Eqn. 1 ----> 4y = x
Eqn. 2 ----> 5x-10y = -50
(Simplifying eqn.2 further)
[tex]=>5(x-2y)=-50[/tex]
[tex]=>x-2y=\frac{-50}{5} =-10[/tex]
(Substituting the value of x from eqn. 1)
[tex]=>4y-2y=-10[/tex]
[tex]=>2y=-10[/tex]
[tex]=>y =\frac{-10}{2} =-5[/tex]
Now, substituting the value of y in eqn. 1 ,
[tex]x = 4*(-5)=-20[/tex]
