Complete the Next Step: A partial solution to the equation −9 + 8v = 7 + 4v is given below. Choose the step that is missing from the solution.

−9 + 8v = 7 + 4v
4v = 16
v = 4

WHICH ANSWER IS IT? :

8v = −2 + 4v

−9 + 12v = 7

8v = 16 + 4v

−2 + 8v = 4v

−9 + 12v = 7

8v = 16 + 4v

−2 + 8v = 4v

anonymous · Answer

The first step is to add 9 to both sides, so you have 
(-9 + 9) + 8v = (7+9)+ 4v
This gives you 8v = 16 + 4v = the 3rd step listed above.
