You can put this solution on YOUR website!
You can write the equation as follow: Change percent to decimals: 46% = 0.46, 56% = 0.56, 47% = 0.47 Let x = the number of liters 46% alcohol solution.\r
\n" ); document.write( "\n" ); document.write( "\"x%280.46%29+%2B+%2840-x%29%280.56%29+=+40%280.47%29\"\r
\n" ); document.write( "\n" ); document.write( "\"0.46x+%2B+22.4+-+0.56x+=+18.8\" Solve for x.\r
\n" ); document.write( "\n" ); document.write( "\"-0.1x+%2B+22.4+=+18.8\"\r
\n" ); document.write( "\n" ); document.write( "\"-0.1x+=+-+3.6\"\r
\n" ); document.write( "\n" ); document.write( "\"x+=+36\"\r
\n" ); document.write( "\n" ); document.write( "You would need 36 liters of 47% alcohol solution.
