Question 133595
{{{w=p(v[2]-v[1])}}} Start with the given equation



{{{w/p=v[2]-v[1]}}} Divide both sides by p



{{{w/p-v[2]=-v[1]}}} Subtract {{{v[2]}}} from both sides



{{{-1(w/p-v[2])=-1(-v[1])}}} Multiply both sides by -1 to isolate {{{v[1]}}}. Doing this will remove the negative from {{{v[1]}}}



{{{-w/p+v[2]=v[1]}}} Distribute and multiply 




So our answer is {{{v[1]=-w/p+v[2]}}}
