Answer:
Infinitely many solutions
Step-by-step explanation:
2y=14-2x
y=-x+7
------------
2(-x+7)=14-2x
-2x+14=14-2x
-2x-(-2x)=14-14
-2x+2x=0
0=0
infinitely many solutions
Answer: -1 would be -d
0 -> d
1 -> f
2 -> stays same
(if this is not the right answer I'm sorry because i learned this awhile ago
