Respuesta :
Answer:y = -7, x = 12
Step-by-step explanation:
y + x = 5
x = 5 - y
y = 2(5 - y) + 11
y = 10 - 2y +11
-y -y
0 = 10 - 3y + 11
21 = -3y
y = -7
-7 + x = 5
x = 12
Answer:y = -7, x = 12
Step-by-step explanation:
y + x = 5
x = 5 - y
y = 2(5 - y) + 11
y = 10 - 2y +11
-y -y
0 = 10 - 3y + 11
21 = -3y
y = -7
-7 + x = 5
x = 12
