-6n+8(-1+2n)=-2(-4n-2)
Show steps

−6n+8(−1+2n)=−2(−4n−2)

Use the distributive property to multiply 8 by −1+2n.

−6n−8+16n=−2(−4n−2)

Combine −6n and 16n to get 10n.

10n−8=−2(−4n−2)

Use the distributive property to multiply −2 by −4n−2.

10n−8=8n+4

Subtract 8n from both sides.

10n−8−8n=4

Combine 10n and −8n to get 2n.

2n−8=4

Add 8 to both sides.

2n=4+8

Add 4 and 8 to get 12.

2n=12

Divide both sides by 2.

n=  12/2

​Divide 12 by 2 to get 6.

n=6

Step-by-step explanation:

answer: the dogs need to shift their focus to human scent.

its because the dogs being trained are for search and rescue thus they need to be able to track humans and their specific scent
