Algebra.Com's Answer #244799 by josmiceli(19441)![]() ![]() You can put this solution on YOUR website! \n" ); document.write( "The key is that if you multiply both sides of the equation by \n" ); document.write( "the same number, the equation does not change \n" ); document.write( "The question then is: \n" ); document.write( "What number do you multiply both sides by? \n" ); document.write( "Let me make up my own problem to show you: \n" ); document.write( " \n" ); document.write( "You must multiply BOTH sides by a number that can be \n" ); document.write( "divided by 2,3,4,5,6, and x without any remainder \n" ); document.write( "I'll takes a guess- how about 30? \n" ); document.write( "Sorry, 30/4 = 7 and 1/2 remainder \n" ); document.write( "How about 60? \n" ); document.write( "Bingo! \n" ); document.write( "60/2 = 30 \n" ); document.write( "60/3 = 20 \n" ); document.write( "60/4 = 15 \n" ); document.write( "60/5 = 12 \n" ); document.write( "60/6 = 10 \n" ); document.write( "But what do I do with the x? \n" ); document.write( "How do I know if x goes into 60 with no remainder? \n" ); document.write( "The answer is to multiply 60 by x, and then I know \n" ); document.write( "60x/x = 60 hence, no remainder \n" ); document.write( "Now I'll do the work: \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "The answer is not important, but the method is. \n" ); document.write( " |
