You can put this solution on YOUR website!
x = ounces of 15% alloy
\n" ); document.write( "y = ounces of 18% alloy
\n" ); document.write( "---
\n" ); document.write( "x + y = 78
\n" ); document.write( "15x + 18y = 17*78
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "x + y = 78
\n" ); document.write( "15x + 18y = 1326
\n" ); document.write( "---
\n" ); document.write( "copy and paste the above standard form linear equations in to this solver:
