Answer:
The solution set would be (-4, 3)
Step-by-step explanation:
To find this, we need to multiply the second equation by 4. Then we can add through.
3x - 4y = -24
4x + 4y = -4
-------------------
7x = -28
x = -4
Now that we have the value of x, we can solve for y.
x + y = -1
-4 + y = -1
y = 3

Answer:
$97.24
Step-by-step explanation:
You can use a direct proportion.
175 is to $52.36 as 325 minutes is to x.
Use two ratios of minutes/dollars:
175/52.36 = 325/x
Cross multiply.
175x = 52.36 * 325
175x = 17,017
x = 17,017/175
x = 97.24
Answer: $97.24
