You can put this solution on YOUR website!
x = gustav age
\n" ); document.write( "y = twins age
\n" ); document.write( "z = sister age
\n" ); document.write( "---
\n" ); document.write( "x = y + 3
\n" ); document.write( "x = z - 5
\n" ); document.write( "x + 2y + z = 39
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "x - y = 3
\n" ); document.write( "x - z = -5
\n" ); document.write( "x + 2y + z = 39
\n" ); document.write( "---
