Answer: choice 1 and 6
Step-by-step explanation:
just plug in 9 for every X making sure they equal each other.
1: positive
2: negative
3: positive
4: negative
:)))
X=-7y+34
x+7y=32
To begin with make the two problems the same kind of problem. By adding 7y on both sides for the first problem.
x+7y=34
x+7y=32
So the correct answer would be no solution because it's the same problem and it can't equal to different answers.
