\n" ); document.write( "x + y + z = 180
\n" ); document.write( "x = 2y
\n" ); document.write( "z = 3y-12
\n" ); document.write( "---------------
\n" ); document.write( "Substitute and solve for \"y\";
\n" ); document.write( "2y + y + 3y-12 = 180
\n" ); document.write( "6y = 192
\n" ); document.write( "y = 32 degrees
\n" ); document.write( "---
\n" ); document.write( "x = 2y = 64 degrees
