x = martin age
\n" ); document.write( "y = angel age
\n" ); document.write( "z = janessa age
\n" ); document.write( "---
\n" ); document.write( "x = y - 2
\n" ); document.write( "z = 3y
\n" ); document.write( "x + y + z = 78
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "x - y = -2
\n" ); document.write( "3y - z = 0
\n" ); document.write( "x + y + z = 78
\n" ); document.write( "---
