When she arrives in the workroom she starts using both copy machines(call them X and Y). During the copying, machine X runs out of paper, so it only printed half as many packets as copier Y.

Algebra.Com's Answer #171758 by rapaljer(4671)![]() ![]() You can put this solution on YOUR website! Copier X printed HALF as many as copier Y, so Y copied TWICE as many as copier X. This might be easier, since I clears the fractions:\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Y=2X, \n" ); document.write( "X+Y= 159\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Substitute Y=2X into the second equation: \n" ); document.write( "X+2X=159 \n" ); document.write( "3x=159 \n" ); document.write( "x=53\r \n" ); document.write( "\n" ); document.write( "Y=2X \n" ); document.write( "Y=2*53 \n" ); document.write( "Y=106\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Dr. Robert J.
