Question

Solve -vp + 65 < 40 for v.Solve 3w - 7r = 15 for r.

Answer 1

Given the expression:

`-vp+65<40`

Solve for v

Subtract 65 from both sides

`\begin{gathered} -vp<40-65 \\ -vp<-25 \end{gathered}`

Divide both sides by -p

Note, the sign < will be >, because of the negative sign

`\begin{gathered} (-vp)/(-p)>(-25)/(-p) \\ \\ v>(25)/(p) \end{gathered}`

So, the answer will be V > 25/p
