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

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.

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

v = - 5
