Answer:
3 days
Step-by-step explanation:
<u>jack</u> emily
55+4=59 28+13=41
59+4=63 41+13=54
63+4=67 54+13=67
Let x - be the number of days
Jack: 55 + 4x
Emily: 28 + 13x
To know when they would have the same amount of money, you make the two equations equal to each other.
Hence:
55 + 4x = 28 + 13x
Rearrange:
55 - 28 = 13x - 4x
Simplify
27 = 9x
Divide each side by 9 to make x on its own (this way we would be able to know the number of days when they get the same amount of money)
x = 3 (3 days)
(-3,5)
4x + 3y = 3
x − 3y = −18
Solve by addition/Elimination
x = -3
y = 5
So,
The solution of the system is (-3,5).
