You can put this solution on YOUR website!
x = cathy age now
\n" ); document.write( "y = mary age now
\n" ); document.write( "---
\n" ); document.write( "x = y - 16
\n" ); document.write( "y + 5 = 2x
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "x - y = -16
\n" ); document.write( "2x - y = 5
