Marshall- 8 hours because 8•6=48
Yolanda- 3 hours because 6•3=18
18•2= 36 18•3=54
4x + 5y = 5 / (-1)
8x + 5y = 25
-4x - 5y = -5
8x + 5y = 25
-4x + 8x = -5 + 25
4x = 20
x = 5
4x + 5y = 5
4*5 + 5y = 5
20 + 5y = 5
5y = 5 - 20
5y = -15
y = -3
8x + 5y = 25
8 *5 + 5y = 25
40 + 5y = 25
5y = 25 - 40
5y = -15
y = -3

Answer:
She made an error when using the zero pair.
Step-by-step explanation:
In step 2, Carianne added 4 to the right side and subtracted 4 on the left side, which is completely changing the equation. By definition, your zero pair must have a difference of zero. She need to add 4 to both sides to continue; when manipulating algebra you need to do the same thing to both sides of an equation, otherwise you're just changing the equation.
