Solve the equation. check your solution. 3v-9v=30

Solve v by simplifying both sides of the equation, then isolating variable
v= -5

Okay, its actually pretty simple.

3v-9v

All we need to pay attention to is the 3 and the 9.  It may actually be better if you write this as 3v + (-9v) just so it makes more sense.

If we add 3 to -9, we will get -6.  So we have -6v = 30

We need to get v by itself to solve for it so if we were to divide both sides by -6, we would get v = -5

We can check this by plugging v into the first equation that you were given.
