Algebra.Com's Answer #78972 by stanbon(75887)![]() ![]() ![]() You can put this solution on YOUR website! Two numbers have a sum of 22. Their difference is 4. what are the two numbers? \n" ); document.write( "---------- \n" ); document.write( "Let the two numbers be x and y. \n" ); document.write( "EQUATIONS: \n" ); document.write( "x+y = 22 \n" ); document.write( "x-y = 4 \n" ); document.write( "------------ \n" ); document.write( "Add the two equations to get: \n" ); document.write( "2x = 26 \n" ); document.write( "Divide both sides by 2 to get \n" ); document.write( "x = 13 \n" ); document.write( "----------- \n" ); document.write( "Substitute that value into x+y=22 to solve for y: \n" ); document.write( "13+y = 22 \n" ); document.write( "y = 9 \n" ); document.write( "-------------- \n" ); document.write( "The numbers are x = 13 and y = 9 \n" ); document.write( "================ \n" ); document.write( "Cheers, \n" ); document.write( "Stan H. \n" ); document.write( " |
