<span>Suppose 2x + y = 15 -----eq 1
. x + 3y = 20 -----eq 2.
Multiplying eq (1) by 1 and (2) by 2 and subtracting the result
We have: 2x + y = 15 and 2x +6y =40.If we subtract, we have y - 6y = 15 - 40.
So we have -5y = -25. y is 5. Substiting into eq (1), we have 2x + 5 = 15. 2x = 15-5 =10 Hence X =5.Hence option B is the correct option.</span>
From c=b-5

2 Pies. If she cuts the first pie for 5 people she only needs one more pie for the 6th person
Answer: 4 7/20 gallons
Step-by-step explanation:
Gallons of soup made = 10 3/5
Gallons that was chicken noodle = 6 1/4
The gallons that wasn't chicken noodle will be:
= 10 3/5 - 6 1/4
= 10 12/20 - 6 5/20
= 4 7/20
Therefore, 4 7/20 gallons wasn't chicken noodle.
