Answer:
x = -1
y = -2
Step-by-step explanation:
To get y by itself:
3x - y = -1
-y = -1 - 3x
y = 1 + 3x
Solve for x with substitution:
2x = 4(1 + 3x) + 6
2x = 4 + 12x + 6
2x = 10 + 12x
-10x = 10
x = -1
Plug the x value into 3x - y = -1
3(-1) - y = -1
-3 - y = -1
-y = 2
y = -2
First you subtract 9 from both sides, so you get -2x=26
Then you divide both sides by -2 which is x=-13
So your answer is -13.

Answer:
A and D. She can make 32 servings in total.
Step-by-step explanation:
This is because if she were to mix up all of the products, she would have 16 pounds of mix in total.
5 1/8 + 4 7/8 + 6 = 16
This is choice A.
Then she must divide this by 1/2 because each serving is 1/2 pound.
16 ÷ 1/2 = 32
That is choice D.
