Algebra.Com's Answer #501141 by JulietG(1812)![]() ![]() You can put this solution on YOUR website! Let A be the larger integer, and B be the smaller integer. \n" ); document.write( "A - 9 = B \n" ); document.write( "5B = 3A + 9 \n" ); document.write( "Multiply the top equation by 5 to make it easier to work with. \n" ); document.write( "5A - 45 = 5B \n" ); document.write( "Substitute the values from the top equation into the bottom \n" ); document.write( "(5A - 45) [this WAS 5B in the equation] = 3A + 9 \n" ); document.write( "5A - 45 = 3A + 9 \n" ); document.write( "Subtract 3A from each side \n" ); document.write( "2A - 45 = 9 \n" ); document.write( "Add 45 to each side \n" ); document.write( "2A = 54 \n" ); document.write( "Divide each side by 2 \n" ); document.write( "A = 27 <<-- \n" ); document.write( ". \n" ); document.write( "Let's make sure it's right by putting it back into the original question. \n" ); document.write( "\"the difference of two integers is 9.\" Therefore, B = 27-9, or 18. <<-- \n" ); document.write( "\"five times the smaller is 9 more than three times the larger\" (5*18) = (3*27) +9 \n" ); document.write( "90 = 81 + 9 \n" ); document.write( "90 = 90 \n" ); document.write( "Success! \n" ); document.write( " |
