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
