Question

How do I work this using the substitution method?

x - y = 3
x + 2y = -3

Answer 1

-3-x/2
x-(-3x/2)
-4x/2
x= -2
-3(-2/2)

Answer 2

hey dude your answer is here.
x -y = 3
x =3+y
here we have to subsitute the value of x in equation 2
3+y+2y= -3
3y =-3-3
y=-9/3
y =-3
and we substitute the value of y in equation 1
x=3+y
x =3-3
x=0
hence x = 0.and y = -3

hope it helps uhh
