Algebra.Com's Answer #707121 by Boreal(15235) You can put this solution on YOUR website! I am interpreting this as \n" ); document.write( "(1/4x)+(1/(2x+1))=(1/3x) \n" ); document.write( "one has to multiply both sides by the common denominator 12x*(2x+1), not just (2x+1) \n" ); document.write( "3(2x+1)+12x=4(2x+1) \n" ); document.write( "6x+3+12x=8x+4 \n" ); document.write( "10x=1 \n" ); document.write( "x=0.1 or 1/10 \n" ); document.write( "check \n" ); document.write( "1/0.4 +1/1.2=1/.3 \n" ); document.write( "10/4+10/12=10/3 \n" ); document.write( "multiply everything by12 \n" ); document.write( "30+10=40 checks.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " |
