You can put this solution on YOUR website!
x = grandfather age
\n" ); document.write( "y = andrew age
\n" ); document.write( "---
\n" ); document.write( "x = 8y
\n" ); document.write( "x - y = 56
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "x - 8y = 0
\n" ); document.write( "x - y = 56
\n" ); document.write( "---
\n" ); document.write( "copy and paste the above standard form linear equations in to this solver:
