Answer:

8. m=6

9. x=2; Alyssa is incorrect because she subtracted 8 from 16 when in reality she should have divided 16 by 8 to get 2. The real solution is 2 because 8 times 2 is equal to 16.

Explanation:

Question 8:

2m-6=m

-2m -2m (subtract 2m from both sides)

-6=-m

- - (divide both sides by the negative)

m=6

Question 9:

8x=16 (divide both sides of the equation by 8)

8 8

x=2
