Question

If you don't see what it says it's says : equivalent the expression for v= - 6/7

Answer 1

Explanation:

To evaluate the expression for v = -6 / 7, we put this value in instead of v to get

`-12(1)/(2)-3(-(6)/(7))`

Which upon simplification becomes

`-12(1)/(2)+(6\cdot3)/(7)`
`-(25)/(2)+(6\cdot3)/(7)`
`=-(25)/(2)+(18)/(7)`
`=-(139)/(14)`

which is our answer!
