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

x + y = 6
x = y + 2

A.
x + y = y + 2

B.
(y + 2) + y = 6

C.
x + (y + 2) = 6

D.
x = (x – 6) + 2

I think its B

Answer 1

Yep! It's b. :) Simply substituting x with whatever it equals, which is y+2. thus B is correct.
