\n" ); document.write( "Let x=the other number
\n" ); document.write( "2/5(x+30)=18
\n" ); document.write( "2/5x+2/5(30)=18
\n" ); document.write( "2/5x+12=18
\n" ); document.write( "2/5x=6
\n" ); document.write( "multiply both sides by 5 to get rid of the fraction
\n" ); document.write( "2x=30
\n" ); document.write( "X=15
\n" ); document.write( "
\n" );
