Answer:
( -1, 1)
Step-by-step explanation:
Substitute the first equation into the second and solve for x:
x + 2(x + 2) = 1
x + 2x + 4 = 1
3x + 4 = 1
3x = -3
x = -1
Then put that answer into the first equation to solve for y:
y = (-1) + 2
y = 1
You can check by putting those answers into the equations:
1 = -1 + 2
1 = 1
-1 + 2(1) = 1
-1 + 2 = 1
1 = 1
