Algebra.Com's Answer #173327 by mando271(42)![]() ![]() ![]() You can put this solution on YOUR website! 7-2n=n-14\r \n" ); document.write( "\n" ); document.write( "you have to solve this by getting the n's on one side and the whole numbers on the other side.\r \n" ); document.write( "\n" ); document.write( "lets say we want the n's on the left side. We need to subtract n from the right side. whatever you do to one side you have to do to the other.\r \n" ); document.write( "\n" ); document.write( "7-2n-n=n-14-n\r \n" ); document.write( "\n" ); document.write( "7-3n=-14\r \n" ); document.write( "\n" ); document.write( "using the same principle. move the wholw number to the right.\r \n" ); document.write( "\n" ); document.write( "7-3n-7=-14-7\r \n" ); document.write( "\n" ); document.write( "-3n=-21\r \n" ); document.write( "\n" ); document.write( "now divide both sides by -3.\r \n" ); document.write( "\n" ); document.write( "n=7 \n" ); document.write( " |
