Algebra.Com's Answer #629349 by fractalier(6550) You can put this solution on YOUR website! Call the first and second numbers, x and y. Then we write \n" ); document.write( "2x - 5y = 11 and \n" ); document.write( "x = 3y + 6 \n" ); document.write( "Now substitute the second equation into the first and get \n" ); document.write( "2(3y+6) - 5y = 11 \n" ); document.write( "6y + 12 - 5y = 11 \n" ); document.write( "y + 12 = 11 \n" ); document.write( "y = -1 and \n" ); document.write( "x = 3(-1) + 6 = 3 \n" ); document.write( "Your numbers are 3 and -1. \n" ); document.write( " |
