You can put this solution on YOUR website!
x = liters of 9%
\n" ); document.write( "y = liters of 4%
\n" ); document.write( "---
\n" ); document.write( "9x + 4y = 7*3
\n" ); document.write( "x + y = 3
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "9x + 4y = 21
\n" ); document.write( "x + y = 3
\n" ); document.write( "---
\n" ); document.write( "copy and paste the above standard form linear equations in to this solver:

\n" ); document.write( "answer:
\n" ); document.write( "x = liters of 9% = 1.8
\n" ); document.write( "y = liters of 4% = 1.2
