X = -5y
Substitute the value of x in first equation,
x + y = 8
(-5y) + y = 8
-4y = 8
y = -8/4
y = -2
Now, substitute the value of y in 2nd equation,
x = -5(-2)
x = 10
In short, Your Answer would be; (10, -2)
Hope this helps!

Step-by-step explanation:
Answer: $8.75 for 250 vitamins.
Step-by-step explanation:
To find how much each vitamin costs we can divide $5.25 by 150.
5.25/150 = 0.035. So each vitamin is equal to $0.035.
We can then multiply the cost of 1 vitamin by 250.
0.035 x 250 = 8.75 or $8.75.
We can also make an equation for this problem. Let the total cost be equal to y and each vitamin equal to x.
y = 0.035x
So the equation above states that the total cost, y, is the amount of vitamins that are bought.
Answer:
1.42
Step-by-step explanation:
x = original price
x + .06x = 1.50
