Algebra.Com's Answer #496935 by y6n3o9p4(20)![]() ![]() You can put this solution on YOUR website! Let x = the smaller number, and y = the larger number.\r \n" ); document.write( "\n" ); document.write( "Here is the problem written as a pair of equations:\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "One method that can be used to solve this is the system of elimination. Subtract the second equation from the first one to isolate the x variable.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "Simplify: \n" ); document.write( "\n" ); document.write( "Now, plug the number into one of the two equations.\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "Subtract 11 from both sides to isolate the y variable: \n" ); document.write( "\n" ); document.write( "You can check your answer by plugging the numbers into the other equation. \n" ); document.write( "\n" ); document.write( "The smaller number is 11, and the larger number is 40. \n" ); document.write( " |
