Solve the system of equations using the substitution method (pic)
x=
y=

x= -2 and y= 3

Step-by-step explanation:

The given system of linear equations :

By using Substitution method , we substitute the value of y from (2) in (1) , we get

 [Divide both sides by 2]

Now , put the value of x in (2) , we get

∴  x= -2 and y= 3 .
