x = dollar price of book A
\n" ); document.write( "y = dollar price of book B
\n" ); document.write( "---
\n" ); document.write( "x = 3y + 4
\n" ); document.write( "x + y = 72
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "x - 3y = 4
\n" ); document.write( "x + y = 72
\n" ); document.write( "---
