Answer 2
Answer:
We need to solve this by looking at each answer choice.
A.
To solve for w, we need to multiply by -9 on both sides.
So,
This is not a positive solution. So eliminate A.
B.
To solve for y, we need to multiply by -3 on both sides.
So,
This is a positive solution. This is one of our answers.
C. [/tex]
We need to multiply by -5/2 on both sides to solve for z.
This is a positive solution. This is one of our answers.
D.
We need to multiply by 7 on both sides to solve for x.
So,
This is a negative solution. So this is not the answer.
