You can put this solution on YOUR website!
x = liters of 15%
\n" ); document.write( "y = liters of 55%
\n" ); document.write( "---
\n" ); document.write( "x + y = 80
\n" ); document.write( "15x + 55y = 50*80
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "x + y = 80
\n" ); document.write( "15x + 55y = 4000
\n" ); document.write( "---
\n" ); document.write( "copy and paste the above standard form linear equations in to this solver:
