Algebra.Com's Answer #37789 by stanbon(75887) ![]() You can put this solution on YOUR website! 2/5=x-2/20 \n" ); document.write( "I started by multiplying 5 through the problem: \n" ); document.write( "(5)(2/5)=(5)(x-2/20) and got: 2=5x-10/100! \n" ); document.write( "You should have gotten: \n" ); document.write( "2=5x-10/20 because the \"5\" multiplies the 2 but not the 20. \n" ); document.write( "Then: \n" ); document.write( "2=5x-(1/2) \n" ); document.write( "Multiply thru by 2 to get: \n" ); document.write( "4=10x-1 \n" ); document.write( "10x=5 \n" ); document.write( "x=1/2 \n" ); document.write( "Comment: \n" ); document.write( "The Least Common Denominator of your original problem \n" ); document.write( "was 20. You should have multiplied both sides by 20 \n" ); document.write( "to clear away all denominators, as follows: \n" ); document.write( "20(2/5)=20(x-2/20) \n" ); document.write( "8=20x-2 \n" ); document.write( "20x=10 \n" ); document.write( "x=1/2 \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
