Please Help!?!


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


x + y = 6

x = y + 2


(Points : 3)

x + y = y + 2

x + (y + 2) = 6

x = (x – 6) + 2

(y + 2) + y = 6

Substitute \(x\) in the first equation with \(y+2\) from the other equation.
Then you have \(y+2+y=6 \Leftrightarrow \boxed{(y+2)+y=6}\)
