Answer: 20
Step-by-step explanation:
x+y=5
x-y=4
---------
x+y=5
x=4+y
--------
(4+y)+y=5
4+y+y=5
4+2y=5
2y=1
y=0.5
x=4.5
---------
x²-y²=(4.5)²-(0.5)²=20.25-0.25=20
Answer:
Equation: 10+x= 15 +0.5x
Time: 10 days
Amount: 20$
Step-by-step explanation:
<u>Equation for Benito:</u>
<u>Equation for Tavon:</u>
<u>Since the sums equalize at some time, we get:</u>
- 10+x= 15 +0.5x
- x - 05x = 15- 10
- 0.5x = 5
- x= 5/0.5
- x= 10 days
After 10 days, Juan will owe both Benito and Tavon $20
