Algebra.Com's Answer #282072 by Tatiana_Stebko(1539)![]() ![]() You can put this solution on YOUR website! If x gallons of a 14%-salt \n" ); document.write( "then obtain (x+6) gallons of a 17%-salt \n" ); document.write( "x gallons of a 14%-salt contains 0.14*x gallons of solt \n" ); document.write( "6 gallons of a 21%-salt contains 0.21*6 gallons of solt \n" ); document.write( "(x+6) gallons of a 17%-salt contains 0.17*(x+6) gallons of solt \n" ); document.write( "So equation: \n" ); document.write( "0.14x+0.21*6=0.17*(x+6) \n" ); document.write( "0.14x+1.26=0.17x+1.02 \n" ); document.write( "0.03x=0.24 \n" ); document.write( "x=8 gallons of a 14%-salt \n" ); document.write( " |
