Algebra.Com's Answer #218650 by scott8148(6628)![]() ![]() You can put this solution on YOUR website! 14(25%) + x (100%) = (14 + x)(30%)\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "35 + 10x = 42 + 3x\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "7x = 7 ___ x = 1\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "adding one liter of antifreeze gives 4.5 liters in 15 liters of solution or 30% \n" ); document.write( " |
