ether -2 or -3 one of those
Step-by-step explanation:
For this case we have the following variables:
d = distance
h = number of hours
The equation for this case is given by:
d = 10 * h

Answer: B) 6</h3>
===============================================
Explanation:
Add the equations by adding the terms straight down.
The x terms add to x+x = 2x.
The y terms add to y+(-y) = y-y = 0y = 0, so the y terms go away
The constants add to 5+7 = 12
The z terms add to -z+z = 0z = 0 and those go away as well
After all that adding, we have 2x = 12 which solves to x = 6 after dividing both sides by 2.
N-7=-2
addd 7 to both sides
n+7-7=7-2
n+0=5
n=5
