Algebra.Com's Answer #204107 by unlockmath(1688)![]() ![]() You can put this solution on YOUR website! Hello, \n" ); document.write( "So x will be one number and the other number we\"ll call y. We'll set up two different equations to look like this: \n" ); document.write( "x+y>27 \n" ); document.write( "y=x-3 \n" ); document.write( "OK, so plug in the second equation into the first to look like this: \n" ); document.write( "x+x-3>27 Add 3 to both sides and combine terms to get: \n" ); document.write( "2x>30 Divide both sides by 2 to get: \n" ); document.write( "x>15 \n" ); document.write( "Plug this answer into the second equation and we'll get: \n" ); document.write( "y=>12 \n" ); document.write( "Make sense? \n" ); document.write( "RJ \n" ); document.write( "www.math-unlock.com \n" ); document.write( " |
