You can put this solution on YOUR website!
x = 12% acid = 88% water
\n" ); document.write( "y = 100% water
\n" ); document.write( "---
\n" ); document.write( "7% acid = 93% water
\n" ); document.write( "---
\n" ); document.write( "88x + 100y = 93(x + y)
\n" ); document.write( "x + y = 228
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "88x + 100y = 93*228
\n" ); document.write( "x + y = 228
\n" ); document.write( "---
\n" ); document.write( "88x + 100y = 21204
\n" ); document.write( "x + y = 228
\n" ); document.write( "---
\n" ); document.write( "copy and paste the above standard form linear equations in to this solver:

\n" ); document.write( "x = 12% acid = 133 gal
\n" ); document.write( "y = 100% water = 95 gal
