Ответ:
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
Now , put the value of x in (2) , we get
∴ x= -2 and y= 3 .
Ответ:
x 6 0 3 -3
y 0 -2 -1 -3
Step-by-step explanation:
We substitute x value in the equation and find y.
When x =0, -6y = 12 or y =-2
Likewise all pairs are found out.
Similarly put y =0: x = 6
When x =3, 2(3)-6y =12 :y =-1
When x=-3, 2(-3)-6y=12 or y = -3
Plot these on a graph and join the line.
Graph is attached below:
