Let A be the larger number and B be the smaller. \n" ); document.write( "A - B = 10 \n" ); document.write( "A = 2B + 3 \n" ); document.write( "Substitute the known value of A from the second equation into the first \n" ); document.write( "(2B+3) - B = 10 \n" ); document.write( "Add \n" ); document.write( "B + 3 = 10 \n" ); document.write( "Subtract 3 from each side \n" ); document.write( "B = 7 \n" ); document.write( ". \n" ); document.write( "If there is a difference of 10, then A = 17. \n" ); document.write( "Does that work? Is 17 \"three more than twice\" 7? 17 = (2*7)+3 \n" ); document.write( "Success! \n" ); document.write( " |
