Since they both equal P, set them equal to each other, and solve for Q.

\n" ); document.write( "\n" ); document.write( " $\"P=100%2B10Q\"$
\n" ); document.write( " $\"1600-20Q=100%2B10Q\"$
\n" ); document.write( " $\"-30Q=-1500\"$
\n" ); document.write( " $\"Q=50\"$
\n" ); document.write( "Then use either equation to solve for P.
