IF YOU MEAN:
\n" ); document.write( "5X/(3X+1)-1/(9X+3)=7/6 THEN:
\n" ); document.write( "[5X(9X+3]-(3X+1)]/(3X+1)(9X+3)=7/6
\n" ); document.write( "(45X^2+15X-3X-1)/(27X^2+9X+9X+3)=7/6
\n" ); document.write( "(45X^2+12X-1)/(27X^2+18X+3)=7/6 NOW CROSS MULTIPLY
\n" ); document.write( "6(45X^2+12X-1)=7(27X^2+18X+3)
\n" ); document.write( "270X^2+72X-6=189X^2+126X+21
\n" ); document.write( "270X^2-189X^2+72X-126X-6-21=0
\n" ); document.write( "81X^2-54X-27=0
\n" ); document.write( "(81X+27)(X-1)=0
\n" ); document.write( "81X+27=0
\n" ); document.write( "81X=-27
\n" ); document.write( "X=-27/81
\n" ); document.write( "X=-1/3 ANSWER
\n" ); document.write( "X-1=0
\n" ); document.write( "X=1 ANSWER.\r
