Which equation shows the substitution method being used to solve the system of linear equations?



x + y = 6
x = y + 2



A.


x = (x – 6) + 2


B.


x + (y + 2) = 6


C.


(y + 2) + y = 6


D.


x + y = y + 2

Answer 1

Okay. So do you know the difference between the substitution method and elimination?

Answer 2

Substitution is where you have to either find x and y... then plug in one of those in the other equation...

Answer 3

So... we already know x because it says
\[x = y + 2\]

Answer 4

Right?

Answer 5

yes

Answer 6

So now we have to plug in x into the other equation... when we do we would get:

\[(y + 2) + y = 6\]

Answer 7

So... what is the answer?

Answer 8

I just gave you the answer by the way...
