MathBot Answer:
−(2v)−(9−10v)=8v−9 -\left( 2 v \right) - \left(9 - 10 v\right) = 8 v - 9 −(2v)−(9−10v)=8v−9
−2v−(9−10v)=−(−10v+9)−2v=−2v−(5(−2v)+9)=−2v−(−10v+9)=−2v+10v−9=8v−9\begin{aligned}- 2 v - \left(9 - 10 v\right)&=- (- 10 v + 9) - 2 v\\&=- 2 v - \left(5 \left(- 2 v\right) + 9\right)\\&=- 2 v - \left(- 10 v + 9\right)\\&=- 2 v + 10 v - 9\\&=8 v - 9\end{aligned}−2v−(9−10v)=−(−10v+9)−2v=−2v−(5(−2v)+9)=−2v−(−10v+9)=−2v+10v−9=8v−9
