\n" );
document.write( "let x represent the cost a box of envelopes and y the cost of a box of note paper. 
\n" );
document.write( "5x + 5y = 25.95
\n" );
document.write( "5(x+y) = 25.95  
\n" );
document.write( "x + y = 5.19
\n" );
document.write( "y= (5.19-x)
\n" );
document.write( "write as we read***
\n" );
document.write( "2x + 6(5.19-x)= 22.38
\n" );
document.write( "2x -6x + 31.14 = 22.38
\n" );
document.write( "31.14 - 22.38 = 4x

document.write( "8.76 = 4x
\n" );
document.write( "$2.19 = x cost of a box of envelopes
