3x = 27 + 2y
\n" ); document.write( "x + (-7/2)y = -25
\n" ); document.write( "---
\n" ); document.write( "3x + (-2)y = 27
\n" ); document.write( "x + (-7/2)y = -25
\n" ); document.write( "---
\n" ); document.write( "3x + (-2)y = 27
\n" ); document.write( "-3x + (21/2)y = 75
\n" ); document.write( "---
\n" ); document.write( "add:
\n" ); document.write( "---
\n" ); document.write( "(-2)y + (21/2)y = 27 + 75
\n" ); document.write( "(-4/2)y + (21/2)y = 102

\n" ); document.write( "y = 12
\n" ); document.write( "x = (7/2)y - 25 = 17
