Which equation will result if the substitution method is used to solve the following system of linear equations?
x + y = 6
x = y + 2

A  x + y = y + 2
B x + (y + 2) = 6
C x = (x – 6) + 2
 D  (y + 2) + y = 6

anonymous · Answer

C is x=(x-6)+2

anonymous · Answer

d
because if you plug in y+2 for x in the first equation

anonymous · Answer

Well, you are going to be putting one equation inside the other.
Since you already have an x= equation, you're going to put that inside the other equation to get y.
