Question 223744
{{{Q = 20500000 - 500P}}} Start with the given equation



{{{Q - 20500000 =  - 500P}}} Subtract 20,500,000 from both sides.



{{{(Q - 20500000)/(-500) =  P}}} Divide both sides by -500 to isolate P



{{{(-Q + 20500000)/500 =  P}}} Reduce.



So the solution is {{{P=(-Q + 20500000)/500}}}
