x=2
Step-by-step explanation:
- add like terms (3x-9x= -6x, 7-3= 4)
- then move the constant to the right (-8+4=-12)
- finally divide it by 6 which gives you "x"
Answer:
Step-by-step explanation:

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.
Step-by-step explanation:
Question 8:
2m-6=m
-2m -2m (subtract 2m from both sides)
<u>-6</u>=<u>-m</u>
- - (divide both sides by the negative)
m=6
Question 9:
<u>8x</u>=<u>16 </u> (divide both sides of the equation by 8)
8 8
x=2
