You can put this solution on YOUR website!
Set-up the system, and the rest is to solve the system.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x, y, z, how many of each coint 5c, 10c, 20c.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"system%28x%2By%2Bz=14%2Cy=2x%2C0.05x%2B0.1y%2B0.20z=1.75%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Simplify the money count equation.
\n" ); document.write( "\"x%2B2y%2B4z=35\"
\n" ); document.write( "and substitute for y in this and the coin count equation.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"system%28x%2B2x%2Bz=14%2Cx%2B2%2A2x%2B4z=35%29\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"system%283x%2Bz=14%2C5x%2B4z=35%29\"----can you do the rest?
