You can put this solution on YOUR website!
x = Gabrielle age
\n" ); document.write( "y = Mikhail age
\n" ); document.write( "---
\n" ); document.write( "x + y = 77
\n" ); document.write( "x = y + 9
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "x + y = 77
\n" ); document.write( "x - y = 9
\n" ); document.write( "---
\n" ); document.write( "copy and paste the above standard form linear equations in to this solver:
