-15/z=-30/(z-5)
\n" ); document.write( "-30Z=-15(Z-5)
\n" ); document.write( "-30Z=-15Z+75
\n" ); document.write( "-30Z+15Z=75
\n" ); document.write( "-15Z=75
\n" ); document.write( "Z=75/-15
\n" ); document.write( "Z=-5 ANS.
\n" ); document.write( "PROOF:
\n" ); document.write( "-15/-5=-30/(-5-5)
\n" ); document.write( "3=-30/-10
\n" ); document.write( "3=3 \n" ); document.write( "
