The product is 18; \n" ); document.write( "the quotient is 2. What are the two numbers? \n" ); document.write( "------ \n" ); document.write( "Equations: \n" ); document.write( "xy = 18 \n" ); document.write( "x/y = 2 \n" ); document.write( "---- \n" ); document.write( "Solve for \"x\" and substitute to solve for \"y\": \n" ); document.write( "---- \n" ); document.write( "x = 18/y \n" ); document.write( "--- \n" ); document.write( "(18/y)/y = 2 \n" ); document.write( "--- \n" ); document.write( "18/y = 2y \n" ); document.write( "--- \n" ); document.write( "18 = 2y^2 \n" ); document.write( "y^2 = 9 \n" ); document.write( "y = 3 or -3. \n" ); document.write( "------ \n" ); document.write( "Solve for \"x\" \n" ); document.write( "xy = 18 \n" ); document.write( "If y = 3, x = 6 \n" ); document.write( "If y = -3, x = -6 \n" ); document.write( "==================== \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
