Solve for v -2v+v=3

$- 2 v + v = 3$

Add $- 2 v$ and $v$ .

$- v = 3$

Divide each term in $- v = 3$ by $- 1$ and simplify.

$\frac{- v}{- 1} = \frac{3}{- 1}$

Simplify the left side.

Dividing two negative values results in a positive value.

$\frac{v}{1} = \frac{3}{- 1}$

Divide $v$ by $1$ .

$v = \frac{3}{- 1}$

Simplify the right side.

Divide $3$ by $- 1$ .

$v = - 3$
