You can put this solution on YOUR website!
LEt the solution be x
\n" ); document.write( "Equation:
\n" ); document.write( "7.28x+8.4(9)=7.95(x+8)
\n" ); document.write( "7.28x+75.6=63.6+7.95x
\n" ); document.write( "0.67x=12
\n" ); document.write( "x=17.9\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Hence, about 17.9 pounds of solution must be added.
