Hello, \n" ); document.write( "When dealing with adding or subtracting fractions we need the denominator to be the same. \n" ); document.write( "(2x-3)/3-(3x+1)/5 \n" ); document.write( "For this we multiply the first fraction by 5/5 and the second by 3/3 to get: \n" ); document.write( "5(2x-3)/15-3(3x+1)/15 \n" ); document.write( "Now we can rewrite this as: \n" ); document.write( "(10x-15)/15-9x-3/15 \n" ); document.write( "This then can be rewritten as: \n" ); document.write( "(10x-15-9x-3)/15 \n" ); document.write( "With me so far? Combine like terms to get: \n" ); document.write( "x-18/15 \n" ); document.write( "There we go. \n" ); document.write( "Make sense? \n" ); document.write( "RJ \n" ); document.write( "www.math-unlock.com \n" ); document.write( " |
