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

8v = −2 + 4v

−9 + 12v = 7

8v = 16 + 4v

−2 + 8v = 4v

Question

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 

 8v = −2 + 4v 

 −9 + 12v = 7 

 8v = 16 + 4v 

 −2 + 8v = 4v

anonymous · Answer

if you add 9 to both sides you get 8v = 16 + 4v

and after that you subtract 4v from both sides, which then gives you
4v = 16
