What is the answer to the system of equations using elimination?

\[
x + y = 4
\]
\[
y = x + 4
\]

x + y = 4 y = x + 4
x + (x + 4) = 4 y = x + 4
2x + 4 = 4 y = x + 4
2x = 4 - 4 y = x + 4
x = 0 y = 0 + 4
x = 0 y = 4

The solution to the system of equations is x = 0 and y = 4 . This means the point ( 0 , 4 ) satisfies both equations. Thus, the final solution is ( 0 , 4 ) .
