If the sum of the two numbers is 16, find the two numbers. \n" ); document.write( "---------------------------- \n" ); document.write( "Equations: \n" ); document.write( "2x = y+7 \n" ); document.write( "x + y = 16 \n" ); document.write( "------- \n" ); document.write( "Substitute for \"y\" and solve for \"x\":: \n" ); document.write( "y = 2x-7 \n" ); document.write( "----- \n" ); document.write( "x + 2x-7 = 16 \n" ); document.write( "3x = 23 \n" ); document.write( "x = 7 2/3 \n" ); document.write( "----------------- \n" ); document.write( "Solve for \"y\": \n" ); document.write( "y = 2(23/3)-7 = 46/3 - 7 = (46-21)/3 = 25/3 \n" ); document.write( "------------------------------- \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( "============== \n" ); document.write( " |
