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

x + y = 6
x = y + 2

A.
x + (y + 2) = 6

B.
(y + 2) + y = 6

C.
x + y = y + 2

D.
x = (x-6) + 2

Answer 1

@KamiBug I think its A

Answer 2

Take the value of x, (y +2), and plug that in for x in the first equation. :)
(y + 2) + y = 6
A is incorrect b/c it's substituting the value of x in for y instead of x.

Answer 3

the answer is B

Answer 4

Thank u @KamiBug

Answer 5

it is because if you substitute x=y+2 into equation 1 you will get (y+2)+y=6

Answer 6

Ok thx
