\n" ); document.write( "

Let amount of water be W\r\n" );
document.write( "

Solve using any of the two equations:
\n" ); document.write( "
\n" ); document.write( "Equation 1

0W + .34(26) = .22(W + 26)\r\n" );
document.write( "        8.84 = .22W + 5.72\r\n" );
document.write( "        .22W = 8.84 - 5.72\r\n" );
document.write( "        .22W = 3.12\r\n" );
document.write( "Solve for W, the amount of water\r\n" );
document.write( "

\n" ); document.write( "OR\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Equation 2

W + .66(26) = .78(W + 26)\r\n" );
document.write( "  W + 17.16 = .78W + 20.28\r\n" );
document.write( "   W - .78W = 20.28 - 17.16\r\n" );
document.write( "       .22W = 3.12\r\n" );
document.write( "Solve for W, the amount of water

\n" ); document.write( "

\n" );
