Is this the right answer (Solve by substitution)

[From: ] [author: ] [Date: 11-04-22] [Hit: ]
(I know my teacher always makes us do that... even tho its annoying-your answer is right (: to check your answer just subsitute your variables for the numbers you got-Yup, looks good to me ;)-yea, its the right answer.......
x=2y
y=2x+3

Here is what I got:
x=2y
y=2x+3

x = 2(2x+3)
x = 4x + 6
-3x = 6
x = -2

x = 2y
-2 = 2y
y = -1

(-2, -1)

Your work is fine !

You could check the results in the other equation...

y = 2x + 3

(- 1) = 2(- 2) + 3

You are correct! Heres how you check this
-2=-1(2)
-2=-2
