Their difference is 1.7, and their product is 6.3. \n" ); document.write( "what are the two numbers \n" ); document.write( ": \n" ); document.write( "Write an eq for the sum and an eq for diff, add the two equations \n" ); document.write( "x + y = 5.3 \n" ); document.write( "x - y = 1.7 \n" ); document.write( "------------adding eliminates y, find x \n" ); document.write( "2x = 7.0 \n" ); document.write( "x = 7/2 \n" ); document.write( "x = 3.5 \n" ); document.write( ": \n" ); document.write( "Find y \n" ); document.write( "3.5 + y = 5.3 \n" ); document.write( "y = 5.3 - 3.5 \n" ); document.write( "y = 1.8 \n" ); document.write( ": \n" ); document.write( "Confirm this by finding the product: 3.5*1.8 = 6.3 \n" ); document.write( " |
