Answer: -3/10
Step-by-step explanation: A positive and a negative will subtract.
1. Find the common denominator (8/10)
2. simce 8/10 is greater than 1/2 you need to add a negative to get 8/10 a lower value
3. subtract 5/10 or 1/2 from 8/10 to figure out what gives you the correct answer

Answer:
x = 2, y = 9 or (2,9)
Step-by-step explanation:
Hello!
The first equation "y = 5x - 1" is telling us that y is equal to 5x - 1
We can plug in the first equation into the second like this:
2x + y = 13 (we know y so we can plug it in)
2x + (5x - 1) = 13
2x + 5x - 1 = 13
7x - 1 = 13
Now we add 1 to both sides
7x - 1 + 1 = 13 + 1
7x = 14
x = 2
Now we plug in x to find y:
y = 5x - 1
y = 5(2) - 1
y = 10 - 1
y = 9
