You can put this solution on YOUR website!
x = cost of table
\n" ); document.write( "y = cost of chair
\n" ); document.write( "z = cost of fan
\n" ); document.write( "---
\n" ); document.write( "x = 2.5y
\n" ); document.write( "z = 3.5x
\n" ); document.write( "z = y + 589
\n" ); document.write( "---
\n" ); document.write( "put the system of linear equations into standard form
\n" ); document.write( "---
\n" ); document.write( "x - 2.5y = 0
\n" ); document.write( "3.5x - z = 0
\n" ); document.write( "y - z = -589
