Algebra.Com's Answer #150216 by jerrybassmasta(14) ![]() You can put this solution on YOUR website! By meaning more than one variable on one side I figure that you mean the same variable.\r \n" ); document.write( "\n" ); document.write( "For example: let x be the the variable.\r \n" ); document.write( "\n" ); document.write( "4x+7-3x=47\r \n" ); document.write( "\n" ); document.write( "If you have two variables on the same side you take them and either add or subtract them. \n" ); document.write( "So 4x-3x. In this case you subtract and you get x by itself.\r \n" ); document.write( "\n" ); document.write( "x+7=47\r \n" ); document.write( "\n" ); document.write( "Now you subtract 7 from both sides\r \n" ); document.write( "\n" ); document.write( "x+7=47 \n" ); document.write( " -7 -7 \n" ); document.write( "---------\r \n" ); document.write( "\n" ); document.write( "x=40 \n" ); document.write( " |
